Yeah I know a 55 gallon isnt huge but its the biggest I can have. A chain store has a hood and tank combo on sale for 100 so I figured I will pick one up. Whats the most monster like fish that can live for life. was thinking a bullhead. Also whats the cheapest way to filter the tank. Im trying to keep the tank, stand, and filter under 200. I can probably build the stand for 30 so Ive got 75 for the filter. Im open to pretty much any ideas. I was thinking a siphon sump. The most expensive thing would be the pump. Any other ideas.
