what about a fire eel and I was also wondering what type of catfish I could have also gar
Definitely do a fire eel or two, or three. Lol.
They are very personable fish and truly become puppy-dog-like. They can grow to 40” but most top out between 30-36”. I have three right now. I got my first two together and they were only about 4” when I got them. Now, they are pushing 26-27”. They are a very rewarding fish to keep.
Bichirs are also a lot of fun if you want to go with a few of them. I prefer the lower jaws and I don’t think any of them get to big to outgrow that tank.
