Jump-proofing a shrimp tank - tips please


Finley

Recommended Posts

What clever ways have you come up with for jump-proofing a shrimp tank, to protect from losses of jumpy species like Darwin Red-nose Shrimp?

The tricky part is that I want a glass-free method for the Summer time, because my cooling system relies on evaporation using fans across the water surface.  It also needs to look neat, and not cost an arm and a leg.  

Easy, right?!

This is what my tank rim looks like. Usually the water level is a little higher.

I find the shrimp will actually use the airlines and heater cables to climb out. The easiest way to stop that is to make a collar on the lines. You can use a piece of plastic, or tape the lines so the shrimp can't climb but the easiest thing to use is a bread bag tag. They fit neatly onto the airline and heater cable, they aren't too big and unsightly but you do notice them. Also keep your water a bit lower as the shrimp can climb up the glass using the algae . I often see shrimp grazing above the water line.

i do have glass lids so I leave the back one on all year round - the fans can still cool the water - I tape the gaps all around the back glass and rarely lose shrimp that way now. My Tibees used to always go walkabout!

I just went through this problem too with DAS who discovered suicide. I went to Bunnings and got some acrylic/Perspex sheet and cut it to size. I think it was roughly $50 which I thought was expensive but was desperate at the time because I was losing shrimp every night. I also noticed it was at night that they were jumping. I'm not sure how I'm going to go about having fans on it as well, maybe I'll just slide the acrylic forward a bit to leave a bigger gap which I'm hoping will be enough for fan air to go through but could be problem which I'm thinking through now for best approach.

Here's some photos of what it looks like.

And one of my other tanks which needed some customisation because of the light and hoses.

It's not the greatest but has worked for me. I haven't noticed anymore jumpers.

if your going to be relying on evaporation cooling you will need to go with something like fly screen over it. but as Ineke said watch the hoses and any thing else they can get a grip of, if they can climb it they will.

I've seen some great terrarium screen covers, but they cost $$$ and are a finer mesh than I want.  

I suppose I should get creative with some fly screen.  Any ideas for a simple frame construction, to make the thing rigid?

I will also deploy a bread tag :)

Maybe you can come up with a new design for open top tanks that use a fan cooler.

Rather can covering the top surface, build your perspex to sit on the rim in a vertical manner, much like the fencing around a tennis court. So you increase the height of the tank rather than covering it. Leave a cutout the shape and size of the fan cooler.  And cutouts for any tubes or airhoses.

Google DIY tank dividers using mesh and poster hangers from Kmart. The same principle should give you a rigid frame. Or you can use an egg crate cut to size and cable tie/glue the mesh to it.

Spotlight has plastic mesh that I use for dividers with the Kmart poster hangers. To make a larger divider I cable tie two or three sheets of plastic mesh together edge to edge. Easy to cut to size with scissors.

Great idea @neo-2FX easy to cut as well I use sharp tin snips on solid polycarbonate sheet. Normal Perspex needs to be cut with a saw however need to take care that it doesn't vibrate and break. One problem with the thinner standard/normal Perspex is it will bow after a while due to heat even bows without heat depending on thickness.

When I was using fans I just left the tank open -or sometimes just the front lid off and rested the fans on the light so they were angled to the water- they don't need to be straight on the water- it worked well and kept my big tank very stable for several years before getting a chiller.

I did use a saw, special type of saw, can't remember the name now. Was recommended by my father who used to cut it all the time. I did have a few small cracks which I didn't really care about. And yes you're correct. It does bow which I thought was annoying initially but actually worked out well because it allows a little air movement [emoji3] ...for summer I'm thinking to cut a square in the corner for a fan and cover it with some kind of Mesh and that should hopefully be enough along with the bow to push air around.

I did think of using Mesh on top but was worried it would cut out too much light.

      Thats a great photo, beautiful blue bolt, I hope it survived the molt without dropping the eggs! I think I can just about see some black dots (eyes) on the central egg but can't be 100% sure. I used to (and plan to again) do weekly water change of 10-15% but if you do too large or quick (not drip in new water) that would likely trigger a molt. What KH are they in, my new setup is sitting at (and refusing to budge) KH 3 and PH 7.5 so I may have to settle for neocaridina shrimp this time as opposed to the caridina I want, though not looking/deciding just yet, give the tank a bit more of a run in! Tap water here starts at kH 14, tds 320, when filtered goes to KH 0 and PH 6 but when put in the tank keeps going to KH3 and PH 7.5 despite 3 x 50% water changes???? You may be at 'maximum capacity' with only 20L tank especially if the tank is a cube type rather than shallow type?

      Right now this tank only has blue bolts and golden bee (red bolts?).  The eggs start off all brown, but at the end, I notice that some are kind of a clear pink-ish color.  So I don't know if that is the egg color of dud or golden bee.  Picture of shrimp only about half hour before molting. The water is always RO + remineralizer, so it should be ok. The tank seems to still be on a "good streak" ever since I started the regimen of weekly water change, monthly gravel vac and plant trim.  The point being to keep the amount of waste low and removing moss / floating plants so that the nitrates go towards growing algae.  At one point, I had three berried females, but only netted about half dozen babies by the end, due to this early molting problem.  There might be about 30-40 shrimp total in 5 gallons, but still very few full-sized adults.

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?
