hey i have a 46 gallon tank with a 7 inch senegal bichir and 4 inch African grass catfish. i want to add a large mouth bass but idk if they will all get along? Also how fast do bass grow?
If you get like a 1-3" fish you could have it in there for about 6 months? Thats a guesstimate but a 46g wont hold the fish for long. You would need to upgrade to atleast a 250g tank so unless you want to buy one, or put it in a pond. Those are 2 options. Please dont consider releasing it into the wild. Not only could it transfer a non-native parisite or disease, the fish would most likely get killed easily because it has been adapted to tank life.
It depends on the temps you keep your tank. Most Sunfish do best in the Low 70s and most Bichirs do well in the low 80s that limits what you can keep in the tank.
I have 3 LMB in a 150gal. Bought then 15 months ago and they were 2-4 inches. Now they are 7-12 inches and the 150 is looking a little small. I will be upgrading to a 300 soon.
A pumpkinseed will work, they stay fairly small (6-8" is about normal, but freaks happen.), but like any centrarchid can be pretty agressive. A bluegill is even nastier, and grows larger that 8". People, do your homework.
