No problem! It's been about eight years since I had a group of them in a 125 gallon ( alot smaller than your working with ). I had mine with a nicaraguense cichlid male and a couple firemouth cichlids. When a occasional turf war broke out the myrnae would back down to no one lol. Convict like, although as you said I did not have mine with the heavy hitters. They are beautiful fish though.
