i am looking to find a good catfish that will grow large that i can buy at a lfs. i will be going with 2 oscars, a pacu, a bala shark, and 2 convicts. what should i look for.
A 180g is good for a couple of adult Oscars... If you want to add red-tailed or other large cat & a pacu, you should probably be looking for a swimming pool sized aquarium.
