There are some juvenile adoteka for sale online but they are expensive @ 25 pounds for two. I do not have alot of space, just 34 gallons 3ft by 1ft and cannot afford to buy several and wait for a pairing. Am I right in predicting that i am likely to get two males if i gamble? I desperately want to house these fish but do not want a disaster and they will be impossible to take back.
