I realized that while maybe borderline sufficient it is not the best size for him a while after I got him. Unfortunately I have nowhere to go with but I am careful with my fish selection and am trying to make his environment as good as possible.I think it will look great once the plants fill in!
and FYI you should either upgrade the tank or rehome the red tailed shark, he looks like eh is already too large for your tank.
they require at least 55 gallons.
