Hi all I am new here and was told to head this direction from my initial newb post. So here goes [don't be to harsh ] I have a 20 gallon (upgrading soon) I have 2 small orange fish...started with a group of 6 but the others died..these last 2 have lasted for about 1-2yrs now. I have a small white/orange minnow. I also have a porthole catfish, a plecko(got from a friend who was going to flush him, I do know they get big), and an African knife fish(also got from friend before they flushed it). I have had this in my 20 gallon for about 5 or 6 months now. I also have a 10 gallon tank with a male and female fiddler crab.
