Piggy67 - You have a RTGG that is 26-27"? I thought your gourami was an O. Goramy which would be much a bigger fish, right? Once he reached 11"-12", his growth rate really slowed down. He hasn't grown in the last 5 years or so. Maybe age is catching up to him, who knows. It certainly has not been for lack of food or space. He has been in a 150gal for 14 years, pretty much by himself (does not play well with others). Yes about the bubbles. Sometimes he will randomly let out air wherever he is and swim to the top to replenish. He has been doing this as far back as I can remember. Not often, but enough not to be a surprise.
Yanbbrox- I will try to get a better pic this weekend. Can't really say about head to body ratio, but now that you mentioned it , does seem odd. I have had him since he was 3"-4". Badly beat up, but once he got some pounds on , he was doing the beating up (pay-back I guess). He stayed in a 60 gal for a nano second before going to the 150gl where he is now. He grew very quickly to 12" and then everything came to a screeching halt, growth-wise. He's always been healthy and has a bottomless stomach. I am assuming that he is not going to get any bigger. Maybe he is something else and not a RTGG and that is as big as they get. Don't know. The shape of his pectorals are as you see them. They grew curved straight up, so there is very little fin to swim with. Same on both sides. All the other fins grew back normal but those. I am just glad I was able to get him out of that green terror tank in the LFS. He would have died if he stayed in there much longer.
