Hey everyone.
What species would you recommend for a 20g aquarium?
1)Ancistrus sp. Green spotted
2)Panaquolus sp. L002
I would like to try breeding them.
Thanks in advance MIKE

With this choice I would use the given it's most likely smaller adult size which would work better in the twenty. There are some smaller ancistrus but I am not sure if this would be one of them.

Thanks!!!
any breeding tips?
