Silver Dollars.?

Question

I have 2 Silver Dollars in my aquarium, they are just a little larger than palm size. I find them quite strange as I've caught them hanging about upside down in the tank more than once. They don't appear sick and are very alert. Does anyone know why they do this?

Answer 1

they are unusual and often lie flat also, i would check your water quality to be sure though and check they have enough oxygen.

Answer 2

Perhaps they haven't got the Cents (sense) to do any thing else. They may be Australian. Tip a can of Fosters in the aquarium this should liven them up if this is the case.

Answer 3

mine do the same
