Aggressive Guppy?

My 10 gallon tank for the last few weeks has just been stocked with the survivors of the ich seige I went through so over 5 or 6 days Ive removed all the fish and today I got 10 neon tetras but to my surprise my male guppy got very aggressive and nippy, Now I've never had a mean guppy before so does anyone know whats up? I removed the guppy so now I think i'll keep it as it is, 10 Neons and 2 Cories. Its just so bizarre to see an aggressive guppy.

 

Very weird, though i guess it can happen, i have had a nice platy go evil on me before, it didnt last long though, it seemed to sort itself out.

 

I had a female guppy that would give birth then within a couple of days kill the male. You probably just have an aggressive guppy.

:shock: Thanks for the advice, The evil guppy now has a 3 gallon all to himself.

lol, just be sure to watch the ammonia levels in tanks 3 gal and under, my 2.5 gal with lots of water changes had a major ammonia prob. i found out to late.

 

Lol hes come rather close to deep 6'n it a few times so I cant say I'd be crushed if he were to pass on.
