Hey Charles I used to keep common toads when I was a nipper, cool.

The
Leucaspius looks interesting too; is that as big as they get?
Have to say I also found the initial lack of interest in this thread a bit weird; these are some of the rarest fish in Europe. *shrugs shoulders* I think what Charles said is right; tropical species seem to garner interest more easily for some reason. Mick I think we three may well be the only folk in the world keeping these in aquaria.
I've said this elsewhere but the habitat is beginning to be destroyed too; it's a very fragile, seasonal river ecosystem which becomes almost completely dry in summer. This is not usually a problem but this year someone is allowing horses to graze there, literally in the river bed, which is now covered in their poop. If too much of that gets into the tiny pools where the fish survive the summer they may even be wiped out this year imo.
