Panda Corys Barbells

[jenjen_82]

Hi I have a few panda corys 1 is bigger then the other and the barbells are nice and long. The other 2 are smaller and there barbells are proper short. They are on gravel substrate which is smooth. I was wondering if different sexes have longer barbells and are different sizes? Surely if the gravel was damaging them all 3 would have short barbells. I have googled pics of panda corys and a lot are showing short barbells like mine. I've tried catching them to transfer to a new tank but was unsuccessful lol

Barbels vary in length, but short barbels is often,poor water quality,poor diet, substrate which is sharp,gravel being a main culprit, especially corys digging into it can cause them to wear down. Most of my pandas have long barbels and they're mixed sexes.
