Looking good! Where did you get that amazing piece of driftwood?
take the from an angle. this will help reduce the flash and point the flash away instead of reflecting it back to the camera. also turn off the lights in the room before shot.
although your love of cpd is amazing, they will be highly timid in such a tank. rummynoses tend to be fast. most cpd tanks are nano sized and are usually species tank due to their size, food competition and timidness.
whats the size of the pleco?
Take pics with tank lights on at night without flash will come out better usually
