i just got a 29 gallon tank and i have my bichir whos only like 6-7 inches long. im just wondering if this tank is a good size for it? also i wanted to get live plants and wanted to know if there is any specific type of plants that i should get or if it even matters? and yeah i used to have it in a 10 gallon tank and it wasnt that active at all but now is all over the place in the new tank but only sence i put one of my goldfish in the tank with it (used to be a feeder but never got eaten all the way heh they seem to be friends now) so yeah i guess what im getting at is how to know if your bichir is healthy and, is it cool hes in there with a goldfish?
