Well now that I found out that I cant order exodons unless I want to pay ridiculous prices, I am back to getting a piranha. I am looking at getting a single extremely aggressive piranha. The only thing is that ity has to be able to be kept in a 40 gallon tank for life. So far I am between a purple sanchezi and a ruby red spilo. Are there any other small piranha? Which do you guys prefer a sanchezi or a spilospleura?
