I have a 29 gallon aquarium, it has 4 harliqaiun rasboras and 7 zebra danios and 1 hellboy betta. My betta named pete, doesn't allways get to the food because my other fish are very energetic and really go after the food I have tried to feed him at another part of the day but it didn't really work. He allways looks hungry. Anything else I could try to do??
