We recently set up our first tank. It is 20 gallons and originally only had two black and two silver mollies. We added two albino catfish to help with the extra food at the bottom of the tank (at least that is what we were told they would do!). Yesterday I found two (so far) fry, which I wasn't expecting and also found one of my catfish had died and it appears that his tail fin has been chewed on. I usually clean my tank on Fridays and now I am afraid to clean it and risk vacuuming up the little guys. I am guilty of getting too excited about wanting fish and did not do my research, therefore I did not realize my fish were live bearing fish! I also did not realize my fish was pregnant. Does anybody have any advice on how to manage my new adventures?!?!?!? Also, any reccommendations for keeping my tank clean, my vacuum takes out a lot of water!
