Sorry for my first post being a question, but here it is anyway.
Also, sorry for the long post.
Background, I was experimenting with reef tanks in the 80s, things have come a long way since.
Recently got back in the hobby.
My setup is a bit different, I guess.
I have a 90 gallon main tank with a 30 gallon sump.
Also, have a 40 gallon frag tank that has a 20 gallon sump, this sump drains into the main 30 gallon sump. Each tank has one independent pump from the sump to the tank. Also, there is a primary pump connected to a manifold. Manifold provides primary circulation to both tanks, gfo reactor, carbon reactor and bio pellet reactor. Have about about 180 gallons in the system.
Both sumps have large refugiums with cheato and other macro algae. Have all sorts of bugs in both tanks and sumps. Good ones.
There is also a skimmer.
There is about 100 lbs of live rock in the large tank an a sand bed. Also lots of dry rock and live sand in both sumps.
The tank is about six months running and very healthy. Main tank has vho and led lights, frag tank has good LEDs. All corals are thriving in both tanks. LPS, SPS, softies, zoas, polyps, mushrooms, there is pretty much two or three of each type, mostly smaller colonies, between the two tanks.
In the frag tank, only fish is a starry Benny. Needs a mate, sooner or later.
Fish in the large tank are a yellow and powder brown tang, two maroon clowns, two cardinals, one red fire fish, diamond Benny, black comb tooth Benny and a baby mandarin. All the fish are 1 to 2 inches, except the tangs, a bit more than three inches. All small specimens.
Some snails, ppmt shrimp and little blue leg hermits in tanks and sumps.
Now the issue.
About six weeks ago I picked up a yellow Corris wrasse from the lfs.
It did very well. Ate frozen food and spent the days picking at bugs on the rocks and sand. Always active and hanging out with the gang. It is a peacefull tank.
One morning about four weeks in, I him dead.
No clue why.
I figured natural causes, so about a week ago, got a replacement.
Same behavior, ate well, played well, no issues.
After a week, found him dead.
Do you think there could be something in my sand killing them while they sleep?
I never saw them sleep in the sand, figured they were in the rocks, but that is where they naturally go.
Also, all my parameters are pretty much pristine. Change about 15% water a week, ca around 480, nitrates, nitrites and ammonia pretty much 0, Mg 1300ish, Phosphats are not 0 but are close and slowly going down, Alk is my only low area currently running about 5.5 and on a slow rise with morning dosing.
Everything looks great and is growing, but this species.
Any ideas?
Again, sorry for the mini novel.
