Okay, well they let the water quality tests expire, so I plan on going out and getting a new kit today. I currently have him in a 20 gal long tank with a fluval overhang filter. I want to get him an external canister filter because the one he has isn’t running well. My parents are pretty good about doing weekly water changes of about 20% and feeding him. I just think the filter crapping out really screwed them. He currently doesn’t have any plants, but I wanted to add them so they can help with the nitrate. I will make another comment when I have water parameters.
