help i am missing fish

my fish seem to be disapearing into thin air i have lost 1 sailfin tang 1 blue damsel and 2 geern chromis they seem to be disapearing at about 1 fish a day all my only fish that is left is my little lawn mower blenny and he is going to the lfs for safe keeping temporarily till i can locate the problem and sacrifice it to the porcelain goddess with 2 flushes for good measure
my ? is what might be doing this and how can i find it

water pram are as follows
ph 8.1
dk 12
cal 320
nitrite close to 0
amon close to 0
nitrate 5

 

maybe a mantis but he would have to be a big one for all those fish

 

this was over the peroid of about 4-5 days and i did put a new peice of live rock in about 7# worth on sunday just b4 disaperances started

 

I would be looking for some sort of invert. I couldn't see this being a fish that is secretley living/killing in your tank. So your not recovering any bodies or pieces of body? See any scales floating?

 

I would say lobster or crab hitch hiker. But its hard to say, your going to have to watch the tank closely. Try at night with lights out, then use a flashlight and see whats creeping around.

 

correct nothin not a scale or fin
when i watch at night should i leave moon leds on or off
they are kinda brright would not need flash light with them on

 

You might try "night spying" with a red flashlight, with all other lights in the area off. I use a white LED light that has a red cover.

 

a friend of mine sujested doing a fw dip on the new live rock peice and see what popes out but it is a very nice peice with many benaficial hitchers and lots of realy nice deep burgany collered corline would a dip kill the coraline

i have a red light from when i was in the army will try that tonight with moons off how long should i wait once lights are out and should i try baiting it with a peice of shrimp to fish in my alga clip

 

Leave your moon lights on... and look around with a flash lite and see what you can find.. and even drop a few flakes of food in the tank so it will entice your preditor if any out...



Best of Luck...

 

maybe your new rock is a huge angler in disguise thats straight gulping down whatever it can at night. thats crazy your loosing so many fish without a trace, at this point I would consider breaking down the tank and dipping all the rock to find the culprit.

how big is the tank anyways, and how much rock is in there?
