Albino bichir
£8.00
Albino bichir .... Polypterus senegalus.
These get a lot of attention in the shop. Peaceful but predatory, they are fine with larger fish and things that are not long and thin.
They do get to around 12 inches, so be aware of that before you put them in with tomorrow's supper.
They do seem to be more active if they have company, so maybe more than 1 would be a good idea, but I dont think they're particularly sociable.
