what kind of fish is good to eat excess fish food of the bottom of the tank?

Cory catfish are one of the best bottom feeders out there in my opinion. They will endlessly hunt the bottom for bits of food as well as any little worms they can find. Personally I would suggest them over any sucker mouthed type cats for cleaning up leftover bits of food.

If you are looking to replace the huge pleco with another type of algae eater in addition to getting something for the flake food, then replace him with a bristle nosed pleco. They are odd looking ( what pleco isn't though) and don't get nearly as large. There are a wide variety of plecos available that don't get big, but the odd or well colored one's usually command a quite high price tag, but bristlenose are usually very affordable.

Crayfish, they will look through every peice of gravel to find food (just be careful, the crayfish might not want the food at the bottom and might attack and eat your fish.

Here is some info on crayfish i made:

Ive had alot of experience with crawfish ( I call them crayfish). Yes, as long as ther whole under side is kept wet .Get a good filter, feed him only a maximum of 3 shrimp pellets every 4 days, DO NOT PUT RAW SHRIMP IN TANK( shrimp carry deseases fatal to crawfish), Put 2 or three live feeder fish fish every week or so , gat him a bubble maker to put oxygeg in the tank, and about 2-3 hiding places. If you evr think of getting 2 crayfish get a 20 gallon( for best results get a 30gallon) and 5 hiding places. Remember this rule, it applies to most species of crawfish: 1crayfish per 10 gallons. If he molts(shed off his shell) he will get bigger and lost limbs will start to regenerate, leave the molt in there so he can eat it and regain calcium from the molt to harden his shell(do not touch it after it molts, its body is fragile at that time.

oh yea, they can live in partly salt water but would prefer fresh.

So They are extremely hardy and can live without food for weeks!

A snail would keep it a little cleaner, however there is still going to be food at the bottom. If it is only a betta try feeding him pellets; they don't make a mess because the betta eats them far too quickly. The problem you are probably having is due to overfeeding. ONLY feed the betta what he can consume in a few minutes; bettas usually eat fast so you should not even have to wait that long. Hope this helps!

WARNING: Plecos are NOT scavengers. I had to learn this the hard way. I was told at the pet store that they were, but mine nearly starved when in w/ my goldfish. On a pleco owners bulletin board, I learned otherwise, but only AFTER they attacked & killed my mama & daddy pair of goldfish (both 11 y/o). Now the plecos are in a tank by themselves & fed veggies, etc. The goldfish get fed a lot less, too, because in the process of visiting to vet w/my big pleco, I learned that the excess flake food (NOT eaten by plecos) was turning the water toxic. LESSON: (1) Overfeeding the top-feeders does not satisfy the bottom feeders. They need their own food. (2) Goldfish & many other fish will eat themselves sick & just pollute the water for ALL their tank mates.

i dont know what the technical name is but a chinese algae eater or rather several of them will help. they eat a range of things including green algae, brown algae, as well as fish food. they also don't get very big. any type of synadonis catfish will help too... they root through the gravel ALOT. also be careful how much you are feeding... if theres lots of food in your gravel, you are probably over feeding your fish. feed them once a day, and only enough that the food doesn't have a chance to reach the bottom.

You should try to purchase a algea eater, preferably a brittlenose catfish. They have been known to clean tanks very well. Make sure there is some algea in the tank for it to feast on though.

I would use cat fish they don't go to the top to eat. They got to the bottom and eat the left overs. They also prevent algae. I know they are not that pretty but give it a try. Also if you want when you get it ask the pet person how big it grows.

I believe corys eat the uneaten food off the bottem...that's what I've used before. Or just don't overfeed.

Gravel Vac. 20% water change every weeks. No fish is a garbage disposal.

A good bottom feeder is a pleco a.k.a. Plecostamus. Another good one is a Chinese algae eater. Cory cats and Clown loaches also work well.
