So I moved my fish into the 90 gallon tank after getting them moved i discovered Ich on a few of my wish I am now treating the tank however i just found out I have a small leak someplace in my tank but not sure where... Am I better to wait until my fish are health then disturb them and stress them out again and run the risk of them getting ich again or should I just do the tank now while the have it and get it over with... I will be moving them back to the 55 gallon temporarerly until I can find and fix the leak...
Honestly, if you bust a seam Ich is going to be the least of your worries. That's the way I see it at least. Put the fish in a quarantine tank and seal the 90.
if you knew where the leak was you might be able to fix it with the fish and water still in the tank....
but since you don't know i would also suggest you move the fish and tear down the tank and repair it..
