So I have 1 turquoise rainbow, my lfs just got in boesemani rainbows, something red something rainbows but they're still in quarantine so I won't be able to get any until Tuesday, what my question is do I have to get 4 specific rainbows like per say I have one turquoise... do I have to get 3 more turquoise and then 4 of the other or will they be fine together if I get another turquoise or 2 and a few boesemani or the red ones I haven't seen them yet so I don't know what they look like but I know The boesemani Rainbows are really pretty.
