Unusually aggressive Aulonacara jacobfreibergi ?

[Rich]

I have a nice big male Aulonacara jacobfreibergi (aka "Yellow Jake")
in my tank, with 3 smaller female peacocks to keep him company.
They've been in the tank for about 4 months now, living peacefully w.
their tankmates and the still-growing plecostamus. Well, over the last
few days, the Yellow has started to be fairly aggressive towards the
other fish, esp. the pleco. He's already chewed up some of the pleco's
dorsal fin, although he's otherwise unfazed. He spends the rest of the
time darting around, extending his fins, "showing off".. is he
courting or something? He's been acting weird. Water's fine.

in my peacock tank, I only had issues like that when overloaded,
overstocked, or room was becoming an issue... eventually had to thin them
out, rearrange the floor of the tank, then it was another 6 months before
they got wiggy again....

if he's beating up on the pl*co, maybe the pl*co's gotta go... he's invading
on jake's space...

hmmm.. good pts. I re-arranged the tank last weekend and it's only been
since then that he's been all territorial. I'll try another arrangement
first, thanks.
