not yet. Here's what I'm planning - it'll just extend the sides of the tank & should still allow for plenty of oxygenation and hopefully will contain the light a little better:
oh yeah, it'll just be an acrylic box that sits over the lip of the tank like a hood with an open top.
The little bugger is hiding out behind &/or under the LR in a corner. The blenny is out a little more, hopefully not claiming the entire tank. I hope he hasn't been spoiled too much by having the tank to himself. If they chase I'm afraid one may jump.
I'm not sure on the acclimation thing on this one. The LFS water was @ 1.022, I lowered the tank from 1.025+ to 1.024+. I floated the bag for about 1/2 hour, added ~5 oz tank water to the bag, floated another 10 minutes or so, then drained the bag & dumped in the fish.
The neon/green star frag (size between tennis & baseball) has about 20% of polyps extended.
I also added a
queen conch snail which I think is safe.
The blenny tooka vent & you could see the mysis eyes still in it

. I think I must've fed him a little too much this morning.
