so i have a 10 gallon tank with 3 guppies. one male and 2 female. my male used to eat everything i give them, now its just the females eating, and when i do feed, the male is always somewhere in the middle of the tank or on the floor swimming around. and if the flakes do float down in front of his, he will eat it and spit it out. and if the pieces are like so tiny, he will eat it... only sometimes, and i tried feeding him frozen bloodworm, he ate it at first, then he started to not eat at all, he looks skinny, he still swims and dances,he just doesnt eat. im worried.
