Hi,I have had this betta a little over 2 weeks now and its fine looked ragged when I bought him. I am attaching a picture in Hope's yall can tell me what to do or if they look normal. He sometimes lays at the top of the water on his side. I have a cycled tank that has been set up for yrs now and all is fine with the ammonia, nitrite and nitrates. Temp is 76. He is in there with 4 small corydoras and 1 cherry barb that is the last of many that I use to have. Nobody chases or nips at each other. I have made sure of that because it was a concern I had. The water gets a 50% wc weekly and a vacume. Plus this betta does NOT like pellets. He loves baby brine shrimp but I know that is not a balanced diet so he can't have that every day. I need to find something he likes to eat. Any suggestions for a balanced food for my guy?
