ok i will try the pea thing first.
i feed the tank as a whole. 50g tall.
3 red eye tetras
2 kribensis (pair)
1 gold algae eater
1 dario boita loach
1 black kuhlii loach
1 synodontis ocellifer catfish
1 yoyo loach obviously
they get about 6 of the small chilid attack pellets 2x day and flakes 2x day, couldnt really measure flakes but its only enought to cover 1/4 the top of the tank after i put em in. and there all gone in under 5 mins. its been the same feeding cycle and feeding times for the last 2 years.
yes he has been fat a long long time, tho its gotten worse lately. so first step peas! tho i think hes just fat and needs a diet in witch case i would need tips on how long he can go without food safely and if a change in foods would help ect.
he can move just fine, as far as i can tell. besides being too fat to fit in some places lol.
i dont have a tank to quarenteen him in

this is my only freshwater tank, the rest are saltwater.... and in no way do i want to get rid of it.
