Okay well I made a post about building a tank in the summer. I found a 150 at pet smart that's on sale, it's standard 4/2/30 or whatever I'm pretty sure. They also had a 125. If I was to just buy s tank instead of building, what would be best? I have a lap bichir and I would like to keep him in either for life, if he would be comfortable in either. Probably just gonna get a single big cichlid and other tropical fish, and more bichirs if it's possible. Any opinions appreciated thank you
