Bronze Corys

[rach125]

Hello,

I have a 20 gallon long tanks, and as per some great advice from others i have stocked it with a group of 6 bronze cories. One of them is a rehome and is absolutely huge in comparison to the rest! I have found that one of the other copies will not leave this big one (I have named him brutus!) alone at all. Is this normal? he keeps swimming away and hiding among the plants but this little fish keeps with him. Could it be that they are going to try and breed or something? Im very new to fish keeping so any advice is greatly welcome. I am currently cycling a 29 gallon long tank, which I will be transferring the copies over to eventually to have a little go at breeding them.

Thank you in advance guys and gals

It sounds pretty harmless to me. Corys really don't have any aggression in them at all, so I don't think anything harmful is happening. They will frequently follow each other around. You could be right and it may be the start of breeding behavior. Brutus may be a female.

females tend to be larger and more plump than the males.

Ah thats probably what she is! Brutus doesn't seem like such a good name now!
