I've had this blennie almost since set up, got him from the local
beach, at first he was this little brown and white thing, but now...
s/he's grown really big and gotten different shaped fins, more
colours and markings etc, yet the other one (who looks very similar)
has stayed very small.
Do blennies operate the same as clowns ie. girl gets big, male stays
small? I have another blennie (this one is dark brown all over) who
has grown bigger and changed etc too.
My question is about his/her behaviour. My tank isn't in the best
condition, I have just moved house and tank and the two or so weeks
before i didn't really see the little guy much, but when i saw him
again he's changed quite a bit. He's probly about 10cm and the
little one's about 6cm long, inc tail. Is this like a maturing thing
they do? Also he's been hiding out in the hole/spot in the LR
almost seems to guard it, hangs around there a fair bit, peeks out
then hides back in the hole. He was acting strange the other week
when next to the little brown/white one. Almost showing off,
I read in one of my books that s/he mite be breeding? Is this a
possibility? If so, what do I have to look out for? Its difficult
to check out his hiding spot as its at the back of the tank against
the wall, but i'll sure try.
Any comments / suggestions are greatly appreciated.
