In my classroom I have a 75g display with a 20g sump. In this tank I have about 100 lbs of LR and a BEAUTIFUL Lionfish. I used to have an eel but it died a year ago over Thanksgiving and I also had a Spotted Puffer that developed the oddest skin disease and died over Christmas a year ago.
This Lion has been with me for almost 2 years and is almost a foot long. Wonderful appetite, eyesight is a little "off" for some reason but respects me when I'm feeding or cleaning the tank and has never offended me except he ate a hawkfish I thought would stay out of his way!
The LFS has a Sea Goblin in and I was wondering if that would make a good tank mate for the Lion. I figure the Sea Goblin has it's own venomous defense, it hides in the sand AND my Lion doesn't have the best eyesight.
What are your thoughts? If it's a "no" to the Sea Goblin, what other choice would you offer besides the typical Predator Tank setups out there?
