Wow! Nice looking couple of giants! The lighter color substrate really brings out the color of the L160. Perhaps get him a lil fatter and see if you can get him to look like a durian?
I do notice with my L185 and L282, they bigger they get, the more docile they get. The panaques are a different story....
Nice 282! How long have you had it and what has its growth rate been? I have 8 that I got at about 4" and their growth rate varies quiet a bit between fish over the last 3 years. I think my biggest ones are only 10 to 11". They have been in the same species tank for about 2 years and I'm not looking forward to moving their spikey little bodies.
