Just a quick one i have currently 3 batches of fry in a grow out tank that has only 2 BN cats in there and im pretty sure that they are picking off some fry. It is hard to tell cause there would be 100+ or so fry but im sure there is less than when they were first hatched , i have lost maybe 1 or 2 a day on the bottom. Have you guys found that bn prey on fry particularly at night. I may need to put them in another tank.
The fry are Hongi , nyeri and A. Maleri so small but not helpless
