so this is my bfs issue first off, but a couple days ago (maybe like 4 days ago) my bf got a common pleco from petco at about 5”. he is a beginner at this and did some research and really wanted one, the lady gave us her recommendations which were hardly any and placed the pleco in his tank that had a turtle filter at the time. one day later, he got the correct filter for his 20 gallon tank (we know this size isn’t okay now) and a day after that a heater (that doesn’t really seem to work). today after getting 2 small angelfish, the pleco began to “faint” here and there. it basically looks like he’s dying but trying super hard to stay alive. he sometimes will also go up to the top for air then kind of just floats here and there and will swim for a sec. he hasn’t latched onto the wall or anything else but is still moving but hardly. we have been feeding algae disks and trying to feed him zucchini but he hasn’t gone for it. we want to save him but know a lot will need to be done for this. please give recommendations.
we currently have 3 goldfish, an albino baby pleco (maybe 2”), 2 small angelfish, & the sick common pleco
