After much deliberation, today I went out to Petsmart and got some tank mates for my Finley Caviar - (3) ghost shrimp! I made sure I got decent sized shrimps so it ensured they'd live a little longer, and also so the chances of them being eaten are reduced...hopefully lol.
I'm pretty sure I have the "paleo" ghost shrimp and not the imposter, viciously aggressive "macro" shrimp that eats fish. These ghost shrimps are actually very terrified of Caviar - they run away from him when he's coming, and when his tail is towards them they hurrily rush by unnoticed. I'm guessing this is a good sign.
So far, so good I think. For the last 2 or 3 hours Caviar has been chasing them and trying to eat them. I'm getting a little nervous because I don't want him to be stressed all night. If I see any frayed/torn/ripped fins or missing shrimp in the morning, I'm taking them out!
