Gold Barb (Puntius semifasciolatus) are a fairly small, peacefull fish (about 3" max) with a fairly small mouth. Adult Guppies and Mollies would be far too big for the Barb to eat. They will of course eat youngsters (fry) though, as will just about every other species of fish.
Simple answer, No. Goldfish are coldwater fish. They can survive in cold temperatures. On the other hand though, guppies and mollies are tropical fish, need special salt, conditioner and a tank of 25C-27C.
It depends how old they are. Tiger barbs will eat young guppy fry. Tiger barbs will attack adult guppies if the water is overcrowded. However, they won't eat adult guppies.
they should mollies arnt that aggresive but if the guppies are small enough it is possible the mollies will eat them but its not likely
The puffer loves live food and will eat anything smaller than it is, it is one of the few freshwater fish that has teeth.
Members of Poecillidae, mollies included, only eat each other if the others are babies, or dead. But most likely, he jumped out.
mostly smaller fish like mollies guppies snails and otocinclus
Guppies would show a lot of different colours whereas the molly doesn't have as many colours as the guppy. Guppies and mollies however are said to be delicate fish so you must be careful what you put in your tank. Male fighting fish would think the brightly coloured guppy tails are other male fighting fish and would try and fight them. Mollies would tend to nip at fish with long fins. Both mollies and guppies are friendly. They are both active and eat a lot.
No. Guppies need a heater, whereas gold fish will overheat. Also, they will eat the guppies.
Guppies are great community fish and can live quite happily with most Tetras, Rasboras, Barbs, Anabantids, Dwarf Cichlids, Danios, Corydoras and many other species provided they don't get too big and eat the guppies.
Oscars and piranha think they are delicious and swordtails and mollies pick on them sometimes. Anything that eats feeders will eat guppies
The small white flatworms found in aquariums are planaria. Fish that eat these small worms include angelfish, Betta fish, mollies, guppies, common blowfish, and goldfish.
Fish that have long, wavy fins should not be put with guppies, because guppies will nibble their long fins. Also, many bigger fish will eat guppies. Keep a separate tank with guppies and a few "cleaner" fish, which do not harm guppies.
Adult guppies eat their own babies, and fish like tuna eat guppies.
