I've been reading up on compatibility. Our 1 betta is about to upgrade from a 2.5 gal to a 10 gal tank. I would like to add either some harlequin rasboras or cories. I understand on the rasboras it would be five to six for this size tank...if I went with cories instead, which type and how many?
I don't have another tank, so I really need to do my research and see if this is do-able. We are upgrading for easier maintenance, so I will sell the 2.5 gal after the upgrade.
If the safest thing is just to leave our betta alone in the ten, we can do that. I thought it might be nice to have some more action, but I don't want the wrong kind of action!! Please weigh in. I know this is tough because it might all depend on my betta...in which case, if you think that is the end word on the matter, maybe it's wiser to just leave him by himself!
Please weigh in?
