Hmmm, thats what I thought he might be, but I was hoping he wasnt!
He does a great job of munching up my algae, but has started to get a bit jumpy and agressive. I've only got a little tank, which I'm sure he will get way too big for - I told the guy in the shop what tank I had and said I needed something to eat algae and this is what he gave me. I was hoping he was an otto or something.
Right, any ideas what I do now? I have a 38 litre / 10 US gallon tank with him, a shrimp, 5 x-ray tetras and 1 (but hopefully 2 soon) leopard cories.
Thanks for your help guys!
