I think the Black Diamond sand looks much better in the tank than when it was bare bottom. I was worried that he might have HITH, so I asked in this thread, but I think he's fine.
My flowerhorn always just piled all the gravel in one corner making it look funny and he is way too aggressive for sand as he would just stir it all up and clog filters all the time. I had a piece of drift wood that injured my FH and now it's just bare bottom. Not only for safety but cleanliness also. IDK how big your fish is but when he gets larger he will just destroy everything, even himself if you let him. FH is most aggressive fish I ever seen next to the Dovii.I think the Black Diamond sand looks much better in the tank than when it was bare bottom.

Where is the water level at in your tank? I'm wondering if when he goes to eat he hits his kok on the rim of the tank or on a cover.It kind of looks like he scraped his head again, I think he might just be rubbing it when he goes under the sponge filter. I tried to bury the base of the sponge filter in the sand, hopefully that will help. I just hope that his head doesn't scar. I don't think it will, but I'm just a little worried.
I don't have a cover, and the water level is an inch or two from the top.Where is the water level at in your tank? I'm wondering if when he goes to eat he hits his kok on the rim of the tank or on a cover.
