Yes, they will eat almost any type of flake food, their diet should include a variety of different foods for good health.
yes
Guppies are omnivores and do OK on normal Tropical fish flakes.
No, you should just feed them tropical fish flakes!
Well if you consider that mollies are tropical fish... then tropical fish food (Flakes) are good yes.
They can live together but you will have to be carefull with the temperature setting of your heater/thermostat and try to keep the tank fairly steady at around 75F to suit both species of fish. Tetra Tropical Flakes are a good all round fish food. Bettas are insectivores and need more protein than guppies so it is a good idea to feed the fish a few Betta pellets and live brine shrimp occasionally.
Tropical fish flakes
If you have an over population of Guppy fish you might consider placing one of its natural predators in the tank for only a short time to reduce the over population : Oscar Fish, Jack Dempsey, Cichlids, or Paradise Fish. this new addition will need to be removed after the desired amount Guppies have been reduced.
no they do not eat bread if they do they will die easily.only use fish food flakes they will live longer!
I have tropical fish and i feed them fish food which says on the label 'tropical fish'.But tropical fish that live in the ocean eat either other smaller fish or worms, really anything they can find.
Green spotted puffer fish eat ghost shrimp, guppies and TetraMin Topical Flakes.
I fed mine regular Tetramin flakes for fish. It has a combination of proteins and veggies and good stuff.
If the goldfish is big enough and the guppies small enough, yes the guppies could well be eaten by the goldfish. Also, guppies should never be with guppies are guppies are tropical fish and goldfish are coldwater fish.
Mosquito fish are not Goldfish. They are tropical livebearers. They may eat the goldfish food but it is not the right food for them and so will not be good for them.
