Hello everyone, I am acquiring a new tank on Saturday and I have some questions about it. It is really big, not sure of the exact size but I would say 50+ gallons. It currently has one resident Pleco which I will be inheriting with it. I have really only ever had bettas, I currently have two, each has their own 2 1/2 gallon tank, filter, heater, and thermometer. One of my bettas I have had for 3 years now, so I have had pretty good success with keeping them, and keeping them healthy and alive for much longer than your average betta owner. This new tank is an entirely new adventure for me, I would like some details on Pleco care, and also suggestions for good tank mates to go along with my Pleco. (I DO NOT want goldfish for sure). Specifically, my brother has a small algae eater ( 3, 31/2 inches long?) if I took him, would he and the Pleco get along? or would the Pleco kill the smaller fish? (my brother has had this fish for years, so he is full grown, and will not turn into a giant one) Also I have always wanted one of the "sharks" a red-fin or rainbow-tip one, but once again I didn't know how that would relate to my Pleco, and my ability to get other fish. Thank you!
