I will be using my 55 gallon.
I live in Florida.
I want to know can I keep different livebearers together and or any aggressive creatures.
Also will pea gravel and flourite soil be okay, I know mollies need a different Ph level.
I currently have 5 adult platy, 3 adult molly, 2 adult balloon molly, and 8 adult guppy, 3 small plecos along with over 50+ fry with more being born. I think you should be fine as long as you have a big enough tank if cause they breed like crazy. I do have a few snails that are also breeding and currently have 5 cherry shrimp in a different take waiting for them to breed so I could move them over. I’ve read that molly tend to eat them so I want to have back up just in case.
