Hi,

I was recently given a 90L tank set-up for free by one of my friends but the catch was that I had to take all the fish with it,
Can you guys give me some advice on what can stay and what needs to go?

- 2 silver dollars
- 1 angelfish
- 1 mollie
- 1 swordtail
- 2 guppys
- 3 black widow tetras

You should rehome the silver dollars, angelfish, and molly should be rehomed.

The tetras need to be upped to a school of six as well.

Wow, my eyes must be going bad. I read 90g tank and was wondering why all the suggestions to re home fish. Then I reread and saw the L. Yes they would work in a 200L tank. Guppies need to be in a school also.

Most of the fish would work, but not the silver dollars. They get pretty large and are a schooling fish.

Guppies also aren't a schooling fish. They can be social, but they don't need a school.

Learn something new everyday... I'd get a couple guppies as part of my own stocking plan but they may end up being another fish's dinner.

No they don't, imo. Mine did better though when I got him a buddy. He kept bothering my danio until I got him someone to hang out with.

To the OP, I would up the tetras to six, rehome the swordtails, rehome the silver dollars, and rehome the angelfish.

Don't forget, rehome the molly also

What are the dimensions of the 200 liter (52 gallon)?
There are lots of species of silver dollars, I believe they are often sold as each other. Some get big and some don't. Just to be safe I'd rehome them.

Do you have any idea of what size tank I would need to keep the angel fish. It is the most generic (cheapest) kind available at my LFS. Would I better with a high tank or a long tank?

If they are kept in an odd number, the rest may pair and bully the odd one out to death.
Also, a large group would require a very large tank, imo over 100g.
