My little dottyback that I thought disappeared is starting to come out at feeding time. I'm having to overfeed the whole tank just to make sure it gets enough to eat. This type of fish is supposed to get aggressive but it is too small for now. Woe be it to the other fish when it gets bigger. By then, though, they will be used to one another.
I got one of those back up air pumps and I took a thick walled gray PVC pipe about 1 1/4" dia and cut it just a little shorter than the height of my tank. I drilled two 1/2' holes about a quarter way in from both ends in the side of the pipe. I propped this pipe in the corner next to the overflow with the airstone hanging half way inside the pipe so that when the air turns on it creates a current in the pipe. This keeps the light off of the airstone so the algae will not grow on it. I think it would be clogged in two weeks if it were not dark.
