Boy, stunning fish. I don't know about sexing but that is one gorgeous fish. How big is the tank? What are the tankmates? Thanks for sharing a picture.
Yes he/she is gorgeous, it is in my main tank which is 6ft x 2ft x 2ft. actually many would say that I have far to many fish packed into my tank. However, I have more than double the recommended filtration and a pond UV Filter, and I always carry out my weekly water changes.
I tried to purchase females when stocking in an attempt to reduce conflicts and to this day, I have had no problems, tank is stocked as follows:
2 x salvini Cichlids,
1 x golden Bay Snook
2 Green and a gold severum
2 brown acara
1 x blue acara
1 x Gorgeous Rainbow Cichlid
1 x female red jewel Cichlid (though i am monitoring this as my snook grows!)
1 x Bala Shark (Only survivor of 6 juveniles following 2 weeks of serious overfeeding by a neighbour when on holiday a few years back!)
2 x Synodontis polli / ocellifer hybrids
1 x red tail shark still aggressive despite his tankmates!
1 x Albino Pleco and 1 x unidentified black pleco, (he had been dumped in a bucket outside my LFS which had closed early so i took him home as it was a freezing winters night!
1 x Fire Eel, approx 18inch
Yes, I know there are alot of fish in there but the water quality is good, my fish are fed high quality food and are in great condition, there are very few conflicts and I have numerous other tanks in the event of any issues, I will post some photos later this week.
