So I currently have
1x GBR
8x harlequin rasbora
2x cherry barb (1 male 1 female)
4x Oto
3x Ghost Shrimp
I am having a hard time finding the cherry barbs. I want to have 2 males and 4 females.
I know you were worried about not having enough algae for the Otos, but I have 4 otos now with decent plant coverage in the tank. I see an algae build up again with the 4 Otos, so maybe I can get away with 6 Otos. I LOVE the Otos, so I think I may get 6 Otos total and maybe 6-8 ghost shrimp. I would def be at my stock limit at that point.
The GBR, Oto, and Ghost shrimp are very entertaining to watch.
Very happy with tank right now!!!
