Fish dying

crims04tide · Jul 20, 2020

For the last 3 weeks I have been losing fish one at a time and I don’t w what is going on with them. I talked with my lfs and they didn’t have any idea either so I have turn here to try to get some ideas of why this would be happening. There is no white spots on the fish indicating ich and they are not rubbing/itching themselves, they seem to be fine and eating before I head to bed but when I go to feed them in the morning one will be dead, I have lost 5 fish In this short span.
My water parameters are as follows:
salinity: 1.025
ph: 8.0
calcium: 420
kh: 8.3
ammonia: 0
nitrate: 7
nitrite: 0
phosphate: .03
magnesium: 1230
Any help would be appreciated, thanks

How big is the tank? What are the fish that have died this far?

crims04tide · Jul 20, 2020

The tank is 65g with 5g of water in the sump, I have lost 2 clownfish, 2 bengaii cardinals, a Kole tank and a rainfordy goby. My skunk cleaner shrimp and snails and hermit crabs have no problems in the tank and my corals have the most extension that I have seen since I bought them. Sorry I miscounted by a fish

Anything new added to the tank recently?

Have all the fish that perished been purchased from the same place? If so I don’t think I’d be buying from them again.

The last thing to get added was the Kole tang and it was also the first to die. That is the fish that I tried to a different Lfs and that fish was in there about 3 weeks, but showed no sign of disease or sickness. All the other fish had been in there for over 2 months

I'd probably do a fallow period of fish in the tank like the attached post. Since it's only your fish being affected I would assume its a disease, inverts are more susceptible to water parameters being off. That being said, safe bet would be the longer fallow period.

Sounds like the tang brought something with it.
Fallow period for now.
Fresh water dip new fish from now on and/or quarantine.

That was going to be my next step, I don’t have the room for a quarantine tank right now so I’m trying the herbal ich treatment due to my mandarin still in the tank, but if all else fails fallow it is.
To everyone that has helped thank you it is very much appreciated

What is your TDS reading? Any corals? Unlikely but check for stray voltage?

crims04tide · Jul 21, 2020

I have 3 coral in there right now, pulsing xenia, gsp and frogspawn tank is 3 months old right now teeming with copepods and tigger pods, recently pulled a brownish small starfish out. Will test for voltage when I can get a decent meter, the one I have base reads at .126 when held in the air. Base reading with nothing plugged in was 25v and with everything plugged in it was 47v which seems super high and I’m not sure anything should be alive at that level
