Evil Glow Light!!!

[adcs]

My brother has a 60l tank with a male Betta 6 Glow light Tetras and 2 Cory cats.

One of the glow lights attacks the betta when there is food in the tank and has damaged one of his fins pretty bad.

When did Glow lights start being aggressive?!

Glowlights can be fairly lively, but never seen an aggressive one. I think
you got an oddball. If he continues to be a problem get him out of there.
Hopefully your other 5 are well-behaved. I do like glowlights.

Maybe the Glowlight read this thread...

I think he must have!

Last night, my own Betta went on a rampage and beat up my Angelfish, a Glowlight and a female Cherry Barb after being let out of a 2 day solitary confinement (a breeding net).

I fear a backlash from my Glowlights or the Noens. They out number Mr Betta 11 to 1.

yeah my glowlight is quite aggresive too.he's the only mean one in my tank!
the same thing happened to me when i introduced my betta, the glowlight took a couple of chunks out of his beautiful tail!!!
