I am new to bigger tanks and we are having some issues. Here is the background.
We have a 29 gallon tank, set it up and let it sit about 6 days before we put fish in. The water stays between 72-76 degrees F
We purchased two Blue Gouramis, a black Molly and a White Molly and a Sail fin Catfish (I believe this was the species). We also have two moss balls
We have already lost our Catfish and the Black Molly, however, after checking twice with a pet store, our water is perfect.
Now one of our Blue Gouramis is showing signs of sickness, his fins turning red.
We purchased some Malafix yesterday and have done two treatments, but the Gourami does not seem to be moving to much more than he was, however, the redness has diminished slightly.
Anyone have any suggestions for us? Although some people say they are just fish, it's hard to keep loosing them.
