Mussin, yours looks similar to mine at that size,but he will only get meaner. I have posted pictures of my guy in the past and he is now 12" with the biggest hump now. He get's nastier all the time but tons of personality,not flighty at all. You will not be able to add any descent size fish to the mix unless you can get him introduced earlier rather than later to a compatible mate. Mine is with a 10" female red devil and he loves her.
Feed him quality pellets and he will be spectacular :thumb:
nice. bio gold + is tha **** for color. try pairing it with the hikari discus formula as well. (*** done that with my african peacocks) it helps bring out stunning coloration patterns. just an idea tho. nice fish either way
