My 55g tank is slowly being stocked. I bought two female platies about two months ago, and have received 12 baby platies from them, all doing fine. I then added a juvenile bristlenose and after that, 10 neon tetras. The tetras had been in for about 2 days when I noticed that two of them appear to have ich. (I've never had it before, but after research I'm sure that it is in fact ich.) Stupidly, I did not QT them as they came from the same place and the pet shop uses one big filtration system for all the tanks. I know I should have used a QT, but the neons looked fine before I noticed the spots. I went back to the pet shop today and had a really close look at their fish, and yep, most of them have it. So, I've started raising my tanks temp to kill the ich. I read that salt is not good for the bristlenose, correct? I'm worried about my little platy babies and the bristlenose the most. The adult platies seem fit and fine, and the tetras are probably used to being infested with something or rather. None of the fish are displaying any signs of distress, no odd behaviour at all. However I am a worry wart by nature and I really don't want to lose the baby platies that I have been raising. So far, two tetras have ich (about 5-10 spots) and one baby platy and one other tetra have a spot each. Could I have some advice, please? Reassurance? Your experience with treating ich with heat, especially concerning the babies? What temperature would you recommend I heat to, and for how long? Thank you!
