Royal Grammas - Mixing Several
- Thread starter gusmanda
- Start date
I know quite a few people who have mixed Royal grammas together anywhere from 2 - 7 the trick is to get them all small about two inches. I can't really recommend a number out of experience,but when keeping fish of the same species odd numbers for the most part work better, therefore I'd recommend three over two.
Also, IIRC, they should all be added at the same time.

Adding them small and at the same time will help your chances. I added a pair to my 210. In QT, the smaller one (1") made a leap of faith when swapping tanks during TTM and hit the floor. Injured, the other RG (1.25") beat the snot out of it. I added a divider and the injured RG spent about a month longer in QT than the other one did for full recovery. The smaller one was added to the DT without any issue--there was a moment of introduction but zero aggression even though the larger one had already established it territory--a hole that they now share.

Small is the key here. The smaller the better. Even better is if all are slightly different in size. The other option is one large and several small.
I bought 3 little ones (~1.5") and quarantined them together in a 10 gallon tank. A bigger QT would have been better, but it worked. They quickly worked out the hierarchy and are now all together in a 40B.
As for the number of grammas - that depends on the size of your tank and your rock work. I would say you can go one per 10 gallon of tank volume if you have appropriate rockwork that gives them enough refuge and cover.

While I have heard stories of success keeping multiple grammas, my experience is that they whittle down to at most two. I have tried getting a group of 6 twice, and both times after maybe 6-8 months I am left with 2. First time I got them from separate tanks at the LFS, second time I ordered them together, small size and told them not to let them be apart, but either way, they whittled down to 2. They always hung out together in the same part of the tank, but I suspect they kill each other off over time. I have a 210 with tons of rock and places for them to hide. I have been keeping fish for 42 years now, so not a newbie. Just wanted to tell you my experience.

The key is to get them as juveniles. Royal Grammas are protogynous hermaphrodites, meaning they are born female and will transition to male given the proper social stimulus (one will become dominant and transition).
