Just wondering if they can be fine alone..? recently i had a power out for a few days and it killed 3 but i still have one left and he seems to be doing fine i have 135 gallon tank should i get more?
We had one before and they're pretty neurotic alone. They will school with any type of schooling fish though, as long as you don't get anything they can swallow.
Why not just go get one? The fish will be happier, You get to buy another fish (always a high for me). See your lfs and what is new in there. And maybe even talk some fish smak with someone.
