I had a seahorse tank for about 8 months and it was doing great. All of them were captive bred H. Kuda from www.seahorsesource.com
Then, I went against the rules thinking [eh, it will be fine.. I'll just get a few more captive bred SH's of a different species] even though I knew you werent supposed to mix species.
Anyway I added a few more. They got a disease and almost all died except for 2 H. Erectus... One died a month later and then there was one left.
For some reason [which I forget] I needed to use the seahorse tank for something else so I moved the last remaining seahorse into my 50g.
Then I bought my octopus who was kept in a critter keeper inside of the 50g. [bad decision]
My seahorse decided to hitch onto the top of the critter keeper and got his tail stuck. When I found him i tried to get him loose but it wasnt going to work unless I ripped his tail.
Because of the comotion ontop of his critter keeper my octo thought it was feeding time.. he came up and bit the seahorses tail.
It was horrible and eventually the seahorse was 1/2 dead. Once he died i pulled him out [it was aweful.... I felt horrible afterwards] and then figured... why waist a perfect meal. So into the critter keeper the dead seahorse went and the octo gladly ate him.
It was really sad to watch the seahorse trying to get his tail out of the critter keeper.
Soooo thats the story on how my octo got a $45 exotic meal.
