Shrimps’s predator?


SpringWaterShrimps

Recommended Posts

Hello guys,

I know that some of you would not agree with this, but anyway, i try.

Im starting to have a lot of shrimps... and i would like to select them.. so here come the culling problem.

My question is: is there some fish, between 0-15 gallons, that could be the Shrimps Eaters, even if it’s adult shrimps.

I already have a betta, that i give him some juvenils. I already saw him eat one little juvenils, bit he is not really that effective.

So do you guys know some fish, that could be the solution?

Thanks for that.

Hi there!
I hope i did not misunderstand what you wrote? You are looking to find fishes to help in culling your shrimps?
Hmm if thats the case, i think a small school of community fishes will do the job for you?
I read somewhere that as long as the shrimp cn fit into the fish's mouth, they would eat them.
Or if you dont want the hassel of maintaining more livestock of fishes, i would keep all the culls in a tank and than feed the existing betta those culls daily? Kind of like a live storage of fresh food for the betta.
Or alternatively, i would prefer to pick out the culls and sell them off cheap.
Some hobbyists may be looking to fill their tanks up with shrimps and are not fussy about genectics and colouring.
Hope this helps,
Jo

I have had Betta before (and getting another but thats a different story).

I put the boring brownish/wild type cherrys in the tanks hoping the Betta would dispose of them but as with your experience he pretty much left them alone? I expect he may have had the occasional treat on a new baby one, but if he did I never saw it. It may have been that they were so well camouflaged that he didn't see them but I don't know.

I guess the problem with putting a fish or some fish that can eat the shrimp means they may wipe out the entire collection, though that may be ok if you are just using the fish to dispose of the unwanted shrimps from another tank.

The first Betta I had, I put red cherry shrimp in with him and he went after them, even adults?

That is exactly what i want. I put the shrimps in the fish tank. Not the fish in the shrimp tank. So my goal is that the fish eat all the shrimps. Offsprings or adults one. My betta got lucky sometimes, and got some but defined not enough.
When the lights are off, and my betta is sleeping, i can see that all the shrimps are out and living relax. Bit when the lights are on, i cant see any shrimps at all. They just adapt to that predation.

I didn't mind if all the shrimps weren't eaten as I still believe that they were part of the eco system of the tank and were still doing some good, though they were virtually invisible in my case. As with you, when I put the red cherries (red ones) in the tank the betta went crazy chasing them but they ended up just hiding all day, so I removed them.

Do you like puffers as a friend had those and they attacked just about anything even if it is bigger than them? They are interesting to watch as well? Just a thought!

Yea of course. I plan to have pea puffers for a long time now but even if they attack shrimps, they will not eat them. I dont want that to be a torture for the shrimps.

Are you sure culling shrimps like this is the very last resort?

You can't sell it ? Or sell it to a Local Fish Shop?

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      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!
