If you don't mind off course, can u please share with us (me ) some pic please brengun.Can't see any black seam to the fin so its not L102.
The spots look a bit big to be a L201 and they only grow to 10cm anyway.
I would say you have very rare in Australia Hypancistrus contradens. They gorw to 12-13cm.
Where were you when I was chasing a female of them? Flaming heck I would have paid a $1000 for one. <3
