So the neons have made it through their first day with Ernesto. I bought a mini sunken ship today for them to hide in (Ernesto cannot get into it, he has some plants). So far so good. They seem to be tolerating each other well, and right now the tank is happy.
I have to do a 25% - 50% water change tomorrow (Amonia is in "stress" level). My question here is, is it safe to siphon/vacuum with the fish still in the tank? I do not want to take them out and put undue stress on them if I don't have to. Help appreciated!
