their are many different things you can find in your local pet store, I use Tetra Color Tropical Crisps to feed my tetras, Wardley Shrimp Pellets for bottem feeders, and Baby shrip for smaller breds such as guppies, and goldfish!
fish
They eat like normal fish. Algae, smaller fish, and seaweed.
fish
Well all fish in the ocean eat the gappie fish and the fish that live in the fishtank they all eat normal fish food.
normal fish food
They eat the food that normal fish eat. Like fish food. They can also eat pizza crusts. I have experimented with this at my own home and pizza makes them stronger.
Guppies are omnivores and do OK on normal Tropical fish flakes.
YES, ALL FISH EAT IT AND BELIEVE IT OR NOT ITS PROTEIN FOR THEM.
You obviously did not do your homework when it comes to the fish you have and their needs. Sucker fish do not eat poop or rubbish. (No fish does that) They are tropical fish and they are algae eaters.
If the fish is still getting used to it's surroundings, it might not eat. This is normal. Usually if betta fish are comfortable, they will eat as soon as they smell or see the food.
it depends on the size of the fish and the size of the pig. for example a normal adult shark could eat a small pig.
