thanks!
the little ones (orange like colour) are ~ 4,8" . the big one is ~7,2" .
If these aren't yarelly's which species can it be?
So for sure they aren't suchus. Only B. bagarius, B. rutilus or maybe a unknown species are left.
Do you think there is a different between the "little orange" and the big one?
I tried to make some new photos but it's very very hard because they're in a very ugly quarantine tank.
You can see the difference between the "little orange" ones and the grey coloured big one.
The orange colour is even a bit stronger in real.
After the first day of arrival I must say that they're really social. It seems that they really search for physical contact.
