Your panaque is beautiful! It changes from time to time, mine is gold when it’s out for food and dark when it’s hidden in the driftwood. Guess it’s something about the mood..
not sure about the real name, but the trading name is curare tiger, could reach more than 12'', my pair is 10-11'', very strong and colorful, aggressive but not too much.
First 3 photos are male, last one is female.
