Hey all, I've currently got a 10 gallon established RCS colony to which I'll be adding a couple annual killifish (N. guentheri 'Zanzibar') who are currently about 2 weeks old. Due to their unique lifecycle and short lifespan (<12 months from hatch typically), I have heard that these killifish can be ...ahem... aggressive breeders from an early age. To prevent velvet and other infections, I've heard that adding about 1/2 teaspoon of salt per gallon can help. Has anyone used salt in a cherry shrimp tank, and do you think that this much would be harmful if slowly introduced? I was thinking of setting up a drip with a concentrated salt solution to slowly increase the salt to the target over the course of a day or two. I'm not planning on introducing any salt unless I see signs of velvet, but I'm just trying to plan ahead just in case. If this much salt is unsafe for shrimp in the long run, does anyone knof of any shrimp-safe ways to prevent velvet and prevent infections from fin tears? Thanks everybody!
