Bottom dwellers. That could be any kind of bottom dweller, not just catfish like Plecos and Corydoras. These fish won't eat poop though, they will not keep your tank clean. In fact Plecos are HUGE waste producers, quite the opposite of any cleaner, I have to remove poop from my Pleco tank every day or it starts to pile up!
If you're after a bottom dweller to clean your tank for you, you're out of luck, nothing cleans a tank but you!
No, they will most likely eat your fish.
The turtles will eat the fish.
they eat left over fish food on the bottom of the tank (if in tank)
the craid will eat the fish
Medium fishes eat small fishes as that's just part of the food chain.
Big fishes eat medium fishes as that's just part of the food chain.
Mostly the algae that forms on the sides of the tank and the dead things on the bottom of the tank.
do whales eat lion fishes
If baby guppies are lying at the bottom of the tank they are dead. They tend to stay as hidden as possible in plants as the adults will eat them.
yes it is bad to eat! the greeny grey stuff at the bottom is mold!
Most fish can be fed fish food. If not they feed on algi, a bacteria that grows on the seabed and plants or the glass walls and bottom of a fish tank.
they think your finger is food or something you can eat. i love zz tops shoes.
