I just got 2 ACF and was wondering what kind of fish i could put in with them they are about 1 to 1.5" long now going to put them in a 10 gal. I read that they don't like filters so i wasn't going to put one in. should I put one in if I have other fish in with them? Or should i put them in my 25 gal tank?How often should I feed them? Any other info would be great.
