I have been keeping a Green Spotted Puffer in salt water for several months now on the advice of the folks at pufferlovers.com. He has done well and is growing like a weed. I recently overhauled his tank...got rid of the gravel and clay flowerpot and added about 50lbs of LR
and a sand bed. The rock was fully cured from my other tanks...never saw any trace of ammonia or nitrite. I also added a few hermit crabs and an emerald crab...puffer inspected them and decided they weren't worthy of his attention. He is so messy that something has to be in there to clean up after him. Anyway, I can recommend this type setup for anyone who has or wants to get a GSP...they are great fish and have quite a personality.
Tonight, I added a small snowflake moray to the tank. These will be the only inhabitants. I dropped the water level about 4" and stuffed filter floss in the few tiny holes in the tank cover...yeah, I've scraped a moray up off the floor before. So far, the puffer is ignoring the moray. Anybody else had any experience with a combo like this?
