Goldfish put anything they can fit in there mouths.
They should never be in the same tank because Guppies are tropical fish and like to be kept over 70F and Goldfish are coldwater fish and like to be kept below 70F. So Goldfish should not bite guppies because they should never be in the same tank together...
Only if there is one in a tank they get very fisty , they will bite other fish in your aquarum .
Actually yes, I have baby guppies and 3" long rainbow sharks that swim together If the rainbow sharks bite the guppies tale then take it out But if they've been in there more than a week then leave them in there
Any fish may fight/bite if they are in cramped conditions and/or poorly fed. Guppies are not regarded as fighters but may sometimes do a bit of fin nipping of any fish with long flowing fins including other guppies and Bettas.
They say guppies like a small amount of salt in their water to keep off disease. make sure not to mix fish that bite the fins. and there is a ale to female ratio, i think its 3male to 2 female
Fries (the term for baby guppies), are eaten by older guppies, but guppies are eaten by fish like tuna.
What are guppies
Only guppies breed with guppies naturally.
No, guppies are fish.
Guppies do not migrate.
Guppies are compatible with Bristlenose catfish, the bristlenose being one of a few catfish that can live with guppies because of the guppies' water.
