They have turned into a nice community now.
Nine in total in a 150 UK gallon tank. These are the ones that came out for pictures.
Filtration is by 1 Aqua one Aquis 1250
and 1 Aqua one aquis 2250-UVC
The two males are the top are about 9inches long. They get on well together although the darker one is the dominant male so far.
Sorry for the terrible pics. It did have a couple splits in the dorsal fin when I got it. The Tiger O bugged it a little, but it seems fine now and the red O didn't mess with it at all. Hopefully, it will grow quickly enough for it to stay where it is. The Tiger O will be gone if it starts picking on it again. I know I'm going against the rules only having one in a SA and poly tank. I'll try to get a better pic later. It swims around quite a bit and so far, is eating sinking carnivore pellets.
