I've always fed my fish everyday, and some are getting pretty fat. I was wondering if it would be ok to feed them every other day. The tank is a 40 G. Planted. 4 Boesemani, 1 Turquiose rainbow. 3 Corys, 7 Guppies and 5 Harlequin Rasboras. And Rabbit Snails and MTS.


Tank has been running for a year and a few months.

I don't see any problem with feeding every other day. You could instead decrease the amount of food you feed daily. I would do the later option.
 
I switched from feeding every day to every other about 6 months ago and haven't noticed any difference except slightly better water quality. I do supplement with zucchini though so there's always a slice in there for them to snack on.
 
Omega One SUPER COLOR and Cyclopeeze.

I think i'm going to do the one day fast.
 
I've been feeding my own fish every other day for almost a year now. Haven't had any problems.

Well, the fish I've had that weren't carnivorous at least. Those I decided I was better off just feeding smaller amounts each day.
 
A lot of interesting observations. I saw two studies which said a lot of the same things.

There was a study done on different fish 'types' which found that, as a group, the fish that eat other fish tended to have much larger stomachs (relative to their body) to the rest. In another study, the predators were the ones tending to have the most empty stomachs. The theory is that in nature, predators evolved so they could make fewer catches and also to be able to survive on just one large meal, therefore one large tummy.

In the aquarium there are fish that in nature eat every day. The herbivorous ones are a good example, with the predatory fish eaters being less likely. Fasting may be a necessary part of that groups bio cycle in order to stay healthy. Growing as fast as possible may not necessarily be the healthiest thing for some fish.

Yeah kind of like wolves. They don't get a meal everyday so when they do they gorge then they go days without eating. I imagine it would be the same for large catfish, gars, and other predators.

Naturally, fish like guppies eat and graze all day long. Which means they'll be eating algae as it grows all the time. Even when you don't feed them, they're eating. You can even raise and breed guppies in well-lit tanks with good algae growth and almost never feed them any "food".

I don't know much about rainbows or rasboras.

Cories are pretty chill, I'm sure every other day is fine for them.

Feeding less will help keep the snails down.
