My quarantine tank is almost ready for new fish. I have a heavily planted 20g long with just kuhli loaches so i'd love some activity at the top. I've been looking into espei rasbora, harlequin rasbora, and purple harlequin rasbora. Is there any differences between harlequins and espeis? I can't decide which one I should get and how many would be appropriate.
I had seen neon dwarf rainbowfish at my LPS
that would follow my hand from one end of the tank to another. It was mesmerizing to see a schooling fish do that. Is there any schooling fish suitable for this tank size that has the same behavior?
I was also thinking about getting a little honey gourami as my LPS
has 2 but they're both males.
Any suggestions would be fantastic!
