Hippo has ick in my fish only tank. I have 2 clowns, one diamond watchman gobie, one firefish, one female lyrtail anthesis, and the hippo. All are eating good and active hippo is a pig eats like crazy and flying around all over the tank. My question is Hyposalinity which I've read is a good remedy to my problem. I do have snails and red leg crabs. Will this kill the crabs and snails. I have no qt tank and no medicine until after Xmas. It's hard tosee I the picture from what I've read it's ick not velvet.
