what is better, a guppy, a platy, a molly, or a sward tail?

Answer 1

I all depends on your tank size,
it's just preference, IMO


they have all the same requirements, beside the molly's which enjoy some aquarium salt in the water


Hope that helps
Good luck

Answer 2

I don't consider any fish "better" than any other, although there are some I personally like more than others. Also, one may be more suitable for a tank size, or certain tank mates or conditions though.

All you list are livebearers, and need similar conditions (other than tank size for their respective adult sizes). The males of the swords and mollies may be a little more territorial/aggressive around each other if you have multiple males and females in the tank, but not to any extreme.

For colors, I like the guppies and platys, but I've also bred certain colors of mollies to acclimate to saltwater tanks.

As far as size, if you have a small tank, guppies and platys are probably the best since they stay the samllest, and if you plan to bred them, they'll take up the least tank space (relatively speaking, a trio of guppies can overstock most aquariums in a year's time if you don't have a place to take your fry).

If you're trying to decide which to keep, this is something only you can decide for yourself.

Answer 3

For me, mollies because both males and females are colorful and they have an over all pleasing basic fish shape. A whole tank of mollies of different colors can be very pleasing to the eye!

Answer 4

All great fish and all are community fish and get along well with each other. We have all of the above in our 55 gallon aquarium and they are great!
