Hi folks, need some advice here. I set my 250 lir tank up 6 months ago and it is thriving. I have a low fish density 10 Neon, 10 Harlequin and 6 Corys. I also had 10 cherry shrimp and 15 nerite snails. All are very healthy. Everything I read suggested I would need more shrimp as fry would be eaten by the fish so i was prepared to get more. To my surprise i spotted very young shrimp in the tank. The Neons were eating some but not all. Slowly the population grew until about a month ago when it exploded!
I fished out 30 last week and gave them to the local shop. That was a fraction of my stock which must be 100+ of all sizes. I've tested my water and it's good but am concerned if this explosion continues I'm going to overwhelm the filtration and have a mass die out. So I have two questions:
Is there a rule of thumb for shrimp population to tank size? I've probably got about 200 ltr of open water.
Much as I hate the idea, is there a predator fish I could introduce that would control the young but not the adults or fish? The Neons are trying, read hunting in the plants but clearly many are hiding until their too big.
I can and will continue to supply the shop or preferably local fish keepers but don't think I can keep up with the breeding.
