with all thats going on in my fish world, I keep putting off my native tank i plan on setting in up. I have aquired a 150 XH, like 2 wide, 2 long, and 4 high, maybe not exact mesurments, anyway i have a loveseat in my fish room and this will be right behind it. pretty cool to sit on the couch and look back with bluegill/sunfish. This tank will be bare bottem sponge filtered. How many full grown sunfish could i do in the 150 XH. I'd like to do 6.
