yeah we had dropped the temp on the heater as it was getting to the 30's :/ so it was quite colder than usual. that's what could've been the main contender in producing the ich, appreciate your help, will be raising temp to see if that sees any changes to ridding the ich.Looks like ich to me! I'm currently treating for ich in qt for a new batch of rummynose tetras. Raising the temperature will help speed up the life cycle of ich and eventually eliminate it because it won't be able to reproduce quick enough (I think). Sometimes heat won't work by itself though. Last time I used salt, which worked, but became annoying because there were always mineral deposits on the glass. There are many resources to figure out how to treat ich. You can also wait for someone else to chime in. I'm sure someone has specifics.
