Not sure if this could work..
I have a planted 20 gallon with 5 shrimp and five guppies (one is male). Would it be possible to start a sorority?
If it is not possible because of compatibility, then never mind. But if not possible because of tank size, what would be an appropriate tank size?
If this does end up working out, how do I switch my established/cycled filter to another tank? How do I put the guppies and betta girls together? How do I safely add more fish without messing with the bacteria?
