So I added an overflow to the tank - figured it'd be handy to remove some misc particles the other filters were missing - not to mention keep the surface debris free.
Yes, I know there's food in the water. I put it there. Got a few misc plant bits just tossed into the overflow, some shrimp and a few guppies. Might toss a few snails in there too. Light will be on 24/7, I imagine it'll be an algae forest - which is fine, I'd rather have it in the overflow than the main tank - and it'll help to cut down on excess waste in the water.
The bit you're actually interested in - a week or two (or three?) of feeding chingmix "color boost" & "head huncher"; [yes, I know I need to clean the glass, yay water spots]
I see no significant changes in the nochal hump. I do, however, see that there is more red covering the body of the Flowerhorn. It seems to be slowly spreading to more areas. The fishes colors also change much more rapidly now when I go to hand-feed. In these pictures the pearls look washed out - flash and dirty water (just about to do a change) they're quite a bit more blue in natural light. Starting to see some teeth on the bottom jaw too.
... and a quick side shot of the 30 Tall,
Snails, shrimp, and recently Dwarf Pea Puffers. Snails are now in hiding.
