They don't notice most of the fish. My dad is building the pond for the koi and goldfish. He's happy because it will have a fountain and he always wanted a fountain. And my mom loves my sorority.
For the 20g, 10 rummynoses, 5 kuhli loaches, 3 cory cats, 3 honey gouramis, 3 otos, and 1 fathead minnow. Overstocked, I know. Also double filtered and heavily planted.
For the 29g, 4 guppy girls, 3 dojo loaches, 2 white cloud minnows.
For the 55g, 2 koi and 1 comet goldfish and their new pond home is almost ready!
Then I have maybe 20-30 guppy babies and 18 bettas.
Food or hairballs or just liquid? If he's puking food, it could be his diet and he might need a new food. If it's hairballs, get him a product called Catlax or another hairball laxative. They'll usually lick it right off your finger. If it's just ugly liquid, he needs to see a vet in case tehre's something wrong with his stomach.
