So, I was getting ready to take a few pics of my Rainbows. It was then I noticed it... the white salt grain of doom. I've started raising the temps, but I'm not sure what else to do. I have the tank pretty heavily planted and don't wanna toast all of them. Probably will stick with the Warm Water + Salt method, but key back the usual dosage of salt and hope for the best. The plants are somewhat replaceable, the fish on the other hand, are not.
Luckily I think I've caught it early enough to nip it in the bud pretty quick. Only 2 of the fish had specs, and on each of them a max of 3-4 specs, and all of those were on the fins. I guess we'll see how it goes.
