I'm not quite new to owning Betta's since I owned 3 when I was in fifth grade but then in 2nd semester decided to get my baby Einstein. He got fin rot which is now gone (he scared me there) thus he now is happy. He is a blue, red, and slightly violet Halfmoon. In March I got my other Betta, Comet who is a beautiful Black and Translucent tailed Halfmoon Double Tail. His fins periodically show blue or red (I can't figure out which) I came here looking for answers and finding out ways to improve my fish to the best of my ability.
Both my fish live in gallon tanks which are cleaned out completely every week. The only problem I'm facing in regards to feeding is that Comet seems to only be eating Bloodworms and NOTHING ELSE, whatever I try. So knowing that blood worms are bad when fed many times a week, I just feed him every 3 day. Einstein is as happy as a mouse with his pellets and won't take anything else (I tried, he just chewed it and spit it out) so I'm happy with that.
I shall post in the disease section because I have a feeling that Einstein has popeye (I can't really see) and Comet, my poor baby, seems to be facing fin rot or something of the sort that just won't go away.
