Ahh.. It was a Dovii in that picture. Nice Male. Hope you have a BIG tank. :)

Thank you. yes i have a 900l tank :)

If I'm correct that is only about 230 gallons. You'll need about twice that to keep this guy healthy through adulthood. These guys are a huge responsibility and require large water volumes in a VERY large aquarium or they won't make it. This is the reason you don't see a ton of adult males of this spieces. People keep them in too small of a tank and they just don't survive it.
