Agressive Neon

[ArroWanaWhitey]

i have a school of 5 neon tetras in my 10 gal, one of them is a bit of a wanker and chases the others around all the time.. i had to replace 3 neons because they died of stress. the water was fine. he is the only one being aggressive

I had two little red swordtails (or as I called them, the sows of satan). they killed a shark, two angels, and two goldfish.

i had a guppy which killed 3 cories and a harlequin and he tried to bite me.

We have one quite large neon tetra (bigger than our cardinals) that tends to bully the other Neon/Cardinal/Glowlight tetras but they have plenty of hiding space so we haven't had too many problems yet.

Do you have another tank you can put the agressive one in?

I ended up having to get some danios to be dither fish as my XL female platy was being a bit of a bossy boot. It has worked as she has calmed down a lot and given confidence to the other fish who used to cower in the corner.

What were you doing having goldfish with the other fish anyway ?
