I have a 55gallon sumpless tank, with a pair of clownfish who are the most curious little creatures I have ever seen. Anytime something is in the tank, hand, bubbles, anything they immediately swim over to it and check it out. Is it bad for them to be swimming through new ro
water that is added to top off the tank? I try and stop when they come by, but now it takes me forever to top off my tank. I was thinking maybe I should start doing it at night when they are asleep, but am afraid it may wake them up in the end. How does everyone else do it?
