He behaves normally, eating like theres no tomorrow, isnt skitish, no flicking or scratching, so i think it might be cauliflower disease.
Tank parameters are as follows: PH: 8.0( i think), ammonia:0, nitrIte:0, nitrAte: 20 ppm, temperature: 78 F. It has 60 lbs of live sand, 6 lbs of LR, and 20 lbs of base rock. Via-aqua 300 watt titanium heater, maxi-jet 1200 power head, fluval 304 canister filter, and a seaclone 100 PS( removed right now because of the melafix)
here is a full tank shot, upclose of the reef structure( fake of course), and pics of the damsel and his bump. sorry about the low-res, its as high as my camera will go. ( im using the memory stick on a digital video camera)The bump is the middle "spot" on the photos.






can you tell me what it is and what i should do?
thanks!
