I'll have to post some pictures tomorrow when the water clears up a bit. It's super cloudy right now thanks to a combo of the new sand and the old water used to seed this tank. I actually ended up getting a 20 long because there weren't any 15 gallons there. Can't say I regret it. I got 3 feeder guppies thinking maybe food, or a cool addition if he decides not to eat them. They've all survived so far so I'm thinking I may be able to get a few more and let them breed a bit. I'm sure Zoidberg wont mind the occasional snack LOL. And I know my WTFs will like the treat once in a while too.
I tried a couple live plants in the 5.5 gallon he was originally in. They lasted about a day before they were all uprooted and snipped up. He did have some fun jamming them in the rocks on the outside of his cave though hehe. So no live plants for this set up.
