I have a cool water tank setup with a small pumpkinseed sunfish and a few rosy red minnows. In the summer I'm going to convert it to a native minnow/shiner tank (if you haven't already checked out my previous thread here it is: http/www.fishforums.net/index.php?/topic/431299-a-fish-to-highly-consider/ And I didn't even make a DENT in the beautiful fish species of North America.) So I recently added C02 and some root tabs because my plants weren't doing so well. Now they are growing fine but had some NASTY algae growing all over my plants and rocks and walls. (My light schedule was jacked up, I kept coming home at late hours and turning on the lights at random hours.... I fixed that now though.) So, I put my siamese algae eater and 2 otos from my other tank in this one. The temperature of the tank is pretty consistently around 73-75 degrees F. All of these fish are acting perfectly fine, especially the SAE, he seems to be more active any happy. All 3 of them began working on my algae the second they hit the water. Now my tank is sparkly clean!
Anyways, is this ok for them long term? I'm thinking of keeping them in this tank permanently to keep my algae down, and they seem very happy.
