Inverts disappearing

[a&a2]

Over the years i have had inverts that have gone missing?

 

[btldreef]

That's kind of a vague statement. Are you looking for a reason as to why?
What types of inverts, tank inhabitants, specs, etc are needed

 

[a&a2]

125 gal set up 8 yrs ago. Sal .022 ph8.1 amm0 nitrite 0 nitrate 5-10. Cleaner shrimp, purple lobster, various hermit crabs added over the years have vanished. In my tank now yellow tanh foxface blue hippo sailfin tang perc clown strawberry basslet hermit crabs urchin sally lightfoot crab

 

[1guydude]

im gonna say the culprit is the lobster or possibly the sallylightfoot!

 

[a&a2]

well the lobster vanished a long time ago and the sally light foot crab just got here a month ago. I've been having this problem for awhile. It's like they never last long terM

 

[1guydude]

may be the iodine levels....does anything molt when introduced?

 

[bang guy]

Specific gravity of 1.022 seems a bit low for most inverts. What temperature are you maintaining?

 

[a&a2]

78 to 79

 

[a&a2]

I've had the sally crab for a month and it molted. I do dose iodine every week or two

 

[1guydude]

are u testing for iodine? U really dont need to dose for it imo....just leave a molt in their for like a day or a half a day to replenish the iodine. Thats wat i do at least. Only thing i really dose for is cal&mag, which is in one bottle. I dose about every other week if that. So u dont think something is eating ur inverts, they are just perishing? Ive had animals go mia as well....

I'd suggest a S.G. of 1.026 at that temp for inverts. Just my opinion.
For sure, overdosing Iodine will damage crustaceans, especially shrimp.

They are just going missing. I do not test for it---I thought all verts needed it

Maybe that is what happened to my previous ones? I'll adjust sg. I thought it should always be between 1.022 and 1.024?

 

[1guydude]

It all depends mainly on ur livestock, coral, and temp imo...im no pro and im still learning but i would agree w/ bang that it should be higher...1.025 or 1.024 at least. Take it up slowly

 

[btldreef]

I fully agree with Bang Guy here.
As for the iodine dosing, a) don't dose if you're not testing, iodine can have terrible effects if too much is added and b) water changes usually replenishes enough iodine into the system unless you're doing bi-monthly water changes.
You might not be finding any remnants of the dead critters because you may have enough other CUC members to clean it up quickly.
How long do the inverts live for before they disappear on average?
I'd raise levels to 1.025-1.026. This is the happy medium. It accounts for evaporation and getting a little higher without harm or a little lower without harm. Just out of curiosity, what salt are you using?
