Jul 8, 2013
I just bought my first aquarium. 55g my daughter loves fish so far I have 2 swordtails 2 Dalmatian mollies and 2 sharks not sure what breed they are. Buying more this weekend not sure how many is healthy in this size of tank. Any help would be appreciated I have no idea what I am doing lol
Welcome to the forum! :)

With a new tank I would highly suggest that you take a look at this link before you continue buying fish

I just learned about cycling but I already have fish. What now?! - Aquarium Advice

The sharks you bought are probably red tailed sharks which seem to be the most common. They will fit in a 55g tank but will be aggressive towards each other and will chase around their tank mates. I would suggest just keeping 1 if you really like them.

As for figuring out how many fish to keep take a look at and it will help guide you.
