Well, the moke is actually a retro but he's doing alright so far.
My filters are two eheim 2217's, and 50% weekly water changes. As well as going to be heavily planted.
And thanks on the bichir...tbh idk how much bigger it will get but he deserved to be in at least a 120 if not larger.
One day when I have my own place I do want to do a planted tank with a few big bichirs, but I wouldn't do it I'm anything less than a 180.
