well I decided my red tail shovel nose cat has eaten enough fish and took him in to the lfs today. he was about 12 inches long and got 20 bucks for him. just enough money for me to get 2 new fishes . before I got the red tail shovel nose I had a large pictus cat that some how died when I was on vacation and my dad was caring for the tank and I decided to get a new one since they are so pretty. so he is now in my 55 gallon tank, and also got what my lfs called a red finned nasai or something like that. he just a juvie right now so in my 20 gallon till he gets big enough to go in my 55. and transfered my baby red shoulders to my 55. once the red fin gets big enough I plan to make the 20 gallon a community tropical.
