How many harlequin rasboras can I fit into a 10 gallon heavily planted tank? They will be the only fish in there with nothing else.

I'd say a shoal of 5 or 6 would he happy in there

They are very slow growing and hardy fish. I have 8 in my 55 gal along with a bunch of community /semi aggressive tankmates. I've had mine for about a year and a half and they are barely an inch. So depending on the kind of algae eater and/or catfish you choose (maintenance fish), you would be safe with 8-10. If you have a good filter to handle the bio-load, a few more would be fine.

They are such beautiful fish! I love mine. When they school it's soo pretty.
