no,your probably thinking about simese fighting fish. Answer- Mollies could fight if they wanted to. My mollies fight when they are intruding their partner. They will chase each other and nip each other. They don't kill each other. Don't separate if they chase each other. They are just showing who is the boss of the tank. If they are missing fins and scales you should separate them.
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 killifish like to nip at fins.
mollies are a breed of fish, so there is a variety of mollies including the black lyretail molly, the ballon molly and the dalmation molly. But all mollies have pointed noses and their underbelly curves down but their back is more straight. Male mollies are bigger and thinner compared to female mollies. If you look near its stomach it will have longer fins compared to female.
They are showing off to one another prior to mating.
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.
Ballon mollies can look like that. Look it up. I have a couple yellow and white ones that look orange.
Although they are listed as peaceful, they have been known to nip the fins of guppies when placed together. They are best to have a tank to themselves
pretty much any fish except their own kind, but don't mix them with fish that may nip their fins, such as tiger barbs.
Some fish (for example guppies) have long wavy fins, some other fish such as mollys like to nip at these fins, if your fish are doing this then it would probably be best to buy another tank and separate them.
Yes, Mollies have scales.
Well, the guppies might nip the angelfish's fins, which, in return, would cause the angelfish to chase and possibly eat them. The angelfish would terrorize the danios and tetras by chasing them. Quick side note: if you are planning on keeping a platy, I really wouldn't keep one! They're quite social fish, and they like to be in small groups. Basically, the angelfish will chase any small fish. The biggest problem you will encounter with this aquarium setup is the fight between the angelfish and the betta. I know from experience-I kept an angelfish and a betta together in a tank myself, and the betta ended up dying. The angelfish will nip the betta's fins, and the betta will nip the angelfish's. They will chase each other and bite a lot. My betta had fin rot and died because the angelfish had caused the fin rot to grow due to the fact that she had torn off all of his fins. I would definitely rethink this aquarium setup.
