Inert Substrate For Caridina? Cycling.


Aqua67

Recommended Posts

Does anyone keep tiger Caridina shrimp on inert substrate successfully?  

I’m 1 week in to cycling a new 3.5 gallon aquarium for 5-10 super tiger shrimp.  I’m using plantable (small pebble) inert substrate which I sprinkled with Bacter AE when I set it up.  I’ve also mixed some Bacter AE with tank water and added it to the aquarium.  Three tiny ramshorn snails are now in the aquarium.

I’m so anxious to add some tigers that right now are being kept with my neocaridina in a tank that is a couple of years old.

Despite the tank being so small, I’ve added a separate tiny nano sponge filter and tiny air pump, in addition to the existing HOB filter with a course sponge over the intake, ceramic rings and the filter cartridge (right now with the carbon it came with - I usually slice the filter and shake all of the carbon out in all of my tanks), plus some old dirty filter floss from one of my established aquariums.  I couldn’t fit all of the filter material I took into the little HOB filter, so I do have a piece of dirty filter floss just sitting in the aquarium also.

There is already many botanicals, some covered in thick fungus/biofilm, which have been soaking in the water for the full week.  That includes catappa bark and leaf, an oak leaf, casuarina cone, alder cone.  There is a lot of plants, although not the stem/rooted kind.  There is a small bolbitis herteroclita, a could tiny windelov ferns, a rosette sword that stays small, a coconut moss covered arch, a rock covered in moss, and a piece of cholla wood covered in black pearl Bruce which had been sitting in an established tank for several months.  One Thrive fertilizer table is sitting under the sword plant and a small dose of Flourish Excel was added which probably bumped up my TDS some.

I’ve added a few drops of household ammonia last week but checked the next day and never had any ammonia reading when I tested.  Now I don’t want to add any more ammonia because the ingredients on the bottle indicate added “fragrance” which I don’t think is good for my aquarium.   I have been added Stability from the start in addition to the Quick Start.  There is no algae growing in the tank yet, but I have left the 6500K lights on 24/7 over this past week.  I realize this may have slowed some bacterial growth initially.

TDS this morning was around 165 and I did a small water change to bring it back down to 150.

I am so anxious to begin to add some tiger shrimp to the new little aquarium.  I did a similar process with my neocaridina back when I first acquired them and my tank was about a week old when I added the bloody Mary’s and I suffered no losses.  Might I be as lucky with Caridina Cantonensis?

Thanks for reading my post.  I attached some pics of the subject shrimp currently living in my neo tank and my new little empty aquarium.

Those are some great shrimp and the tank look awesome!

The tiger shrimp are between neocaridina and caridina when it come to ease and toughness. They should be fine in the neocaridina tank until you are ready to transfer them to their new home.

You may need to drip acclimate them when transferring them if the water parameters of the 2 tanks are different and I would just transfer a couple to start just to check as it hasn't been running for long. Also make sure you have finished with the additives/chemicals (especially ammonia) you are using before adding any shrimps, apart from bacter ae which is ok as I use regularly anyway and the tank is set up and running as it will be regularly, light time etc.. Being a small tank anyway you don't want to risk throwing the balance out by adding too many shrimps in one go at the very start.

You may want to decide on one or other of the filters as you don't need 2 and are making extra work for yourself, but if you decide to remove 1, leave the sponge in the tank for a few weeks for the bacteria balance not to crash etc. From the way you have set it up the tank probably is cycled but there won't be much for the shrimp to graze on yet (another good reason to just do a couple for now). Be very cautious about using plant fertilizers, I know you don't have soil substrate, but I would try NO ferts from the start as the shrimp waste etc will be a source of fert. If you later find you do need fertilizer then be VERY cautious and use as little as you can get away with, but I suspect you snouldn't need any when you have the tank with enough shrimps in it. Aside from that you don't want the plants to grow quickly anyway in a small aquarium as that just makes a lot more work and disturbance.

When dosing bacter ae (or any powder, inc food) I use a wood matchstick or similar, dip that quickly half a cm or cm in the water, then put it into the bacter ae, shake excess off and then swirl the matchstick in the tank, this way you don't get too much in the tank and it gets spread around more, and is just the easiest way all round.

I would add 2 or 3 shrimps and if all goes ok for a week then transfer the remainder? Maybe do a 50%+ water change first because of all the stuff you have been using to get everything started?

Good luck and i'll keep my fingers crossed!

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!

      Hi SKF!   So I bought some PRL (or at least they were sold as such. These claims are dubious in Australia as people don't know much about the genetics, nor do they care as long as they can make a quick buck). After 8 generations of breeding true, I'm having around 1 in 200 throw a much darker red. They almost look like Red Shadows, but I don't know too much about those types of hybrid. Can anyone help with ID'ing the gene?   TIA (First 2 pics are the weird throws, second photo is their siblings and the last photo is the parents)

      Thanks for taking the time to do the update and photo. Very pleased to hear it is now going so well. Different plants have different requirements so you need to check they will thrive/survive with the setup, light requirement/co2 etc or just get more of what you have, there are various Anubias if you want some variety. The number of shrimp shouldn't affect what plants do well! Maybe just get one plant at 6 month intervals and have another go, things change in time and you don't need many in a small tank, and the ones you already have will grow over time as well. Good to hear you got rid of the scuds, I did the same, manual removal when I had them, but I caught it quite quickly and only had substrate in the tank!

      Maybe it’s time to give some feedback. I forgot the time I could see only 2 shrimps, since then the population has grown so much that I gave 30 of them a couple of months ago. Then again now I think the population went over 120 and I am giving again about 70 of them. Not sure why they died in the beginning, maybe they were quite old. They were fairly big! Or it was the planaria? I got rid of them and scuds. The second one was not easy. It was out of control so I emptied all the shrimp population from the tank and poured sparkling water for a couple of hours. Some scuds survived that! But eventually they disappeared in some weeks after manual removal each time I could see one. My only problem is that plants dont go well anymore.  xmass moss, dwarf hair grass and anubia nana go very well but other plants progressively died. (Not suddenly) - Is it due to shrimp over population? - the sparkling water treatment ?  - i can’t see other issue, i provide generous lighting, co, fertilizer (in soil and in water). I have a bit of algae but under control.
