Turned on my lights about 11:50 a.m. and saw my blue hippo just being thrown about the current in the tank. It was all over the place, upside down, sideways...poor fellow

He is gone....don't know why, how, when (well overnight).......

I picked it up a little over a month ago, it was a small one (which I have read many times, have a lower survival rate than the larger ones). A couple of days later I saw it scratch itself against a rock...ICK ....But I rode it out. It stopped scratching itself after a week.....it was eating just fine, was getting a little fat, and swimming around. I have (despite owning a clown tang, who is great in my tank and doesn't mess with anyone) a relatively peaceful tank. The only bully I have in there is a larger chromis who only OCCASIONALLY chases the smaller chromis.

Coincidentally this morning I was testing my parameters for the first time in months....yes, I have become a non/occasional tester.....getting water ready for a 25 gallon water change...and BAM, (the fish ninja) showed up overnight and took the little bugger from me. All my parameters (outside of calcium and alkilinity which I was about to test) tested perfect....

Last time I saw the guy was last night before lights out, just swimming happy (or so it seemed) as can be. It was even getting sucked into the Seio, before I grabbed it, it slipped out of my hand and now under a stack of rocks....

It will be food for the crabs and snails I presume because I can't get to it (unless after the wavebox kicks back on it comes out from under the rocks).

Such is the hobby....
