I doubt it was disease as stated the shrimp began acting erratic then the eating active fish vanished...
Also I tested stray voltage... I don't notice a tingle or anything in the water when working in it and I'm not super electronically inclined. But I tested it with this on the 200 acv and I got .2 to .3 at 250 acv I got 0
No it had no signs I could see.. it was active eating and not skinny nor swollen... no spots or blemishes... and I've searched the area around the tank out a few feet... unless it managed to land in a gap in the wall that's pretty darn small.
Going to test again when the heater is on to see if it changes.
i checked for days afterwards... nothing unusual around the tank.... but there is stray voltage... small small amounts.... but enough it must have messed with the shrimp... and maybe the fish? replacing the wave maker asap.... also going to send out an ATI ICP-OES to check for anything else in the water that may or may not have affected it. If all goes well we might use the tank as a grow out for a pair of clowns (gladiator and a mocha storm) before adding them to the 120 gallon aquarium.
I don’t know how much current would harmful but best not to have any. I would think that it would mess with the fish’s lateral line though.
I saw where a group trying to grow corals for reef replacement where using electric current to make the corals grow faster.
of course this is much to dangerous to use in a reef tank
So I blew up my meter... oops.... finally got another... voltage is now down to to negligible...
I know it's drastically off subject but would the 13.5 be to small to grow out a pair off clowns until they can be added with a 4 or so inch yellow tang
They won’t grow much in a small tank. My first tank was 36 gallon and a pair of Occ. Clowns didn’t get full size. After I upgraded to a 65 gallon they did.
While I was setting up the 65 I had to keep them in a 10 gallon for a few months, they did fine.
Why do you want to keep them separate?
