How Many Fish Can I Get?

[bettaluv]

Hi guys.

Me and my dad bought a 20g tank a while ago, and now we have an undergravel filter or something like that, two air pumps, and a filter that pushes a good amount of current into the water.

My dad now wants to get another filter, so that we have two, but hes going to buy a small one with not much current because I'm purchasing female betta possibly tomorrow or today.

After this, how many fish can I get?

Here's the stock :

Eight Platy
One Swordtail
Two Mollies
One Balloon Mollie
Three Black Skirt Tetra
One Dwarf Gourami <very friendly thoe>
One Cory <small>
(Plus three more platy, once they get older. Still fry)

Thanks,
Mac

You would be best upping the Cories to 5+ as they prefer to be in groups.
Also keep an eye on the Black Skirt Tetras as they are known to fin nip, they also prefer to be in shoals.
You're stocking level is a little high, so I wouldn't advise adding anything else.

i wouldn't add a betta, due to already having gourami and tetras

your list seems to be ok if you make the changes listed above. But I would probably put a female with the male just to keep him happy lol!
