Recent death

[Dennis McGrath]

I have a Biocube 32 that has been looking great with 12 various corals in it, and everything is flourishing. This Saturday I purchased 2 Blue Chromis and this morning both are dead. they seemed fine just the other day. My levels are fine, close to zero nitrates and ammonia. Is there something I should check within the tank that maybe I've overlooked?

Bad shipment/ livestock? Its not necessary that the tank has issues. How long have you ahd the tank running for? It could be the fish fighting each other. I have no experience with chromis, but always heard they tend to kill each other.

I've had the tank for a couple of months. The fish seemed to get along fine, but I'm thinking it might have been bad shipment. I was just reading about how most of them are caught with cyanide.

Speaking to collectors, they don't use cyanide to collect chromis. The method used in that 'study' was a hatchet job, with the alleged methods used to test for cyanide recently debunked.

How long did you have the chromis? Where did you get them? How where they acclimated?

Ammonia should be 0, not close to zero.

If tou had them for months, but they both died in quick succession, that points to a parasite.

Yeah, it can be anything. We do our best to provide a good environment. QT is a good way to know what is happening. I had fish for 6 months and all of a sudden I lost 4 overnight. So give it sometime, watch the same fish 2-3 times before buying it. If you dont QT this is one way and again its not always like this. Good luck on the next purchase.

I heard blue reef chromis are more finicky than regular. Im not sure if that is true. I heard they are bad shippers as well.

I only had the chromis for 3 days before they died.
Got them from a LFS.
Ammonia reads 0 with the API test kit, but I don't know how accurate that is, so that's why I said it was "close to zero".
They were drip acclimated over a 45 minute period.

I had the TANK for months. The fish I only had a few days.

They also could have had ammonia burn in the gills.

I just tested everything and ammonia is still reading zero.

im talking bout when the fish was in transit and then the bag was open then oxygen made thr ammonia toxic

Did you check the salinity of your tank water to the salinity of your LFS? A lot of times the LFS keep their salinity very low to combat parasites. I always quarantine new fish because of the risk of parasites and I can adjust the salinity to the salinity in their bags. Then I can gradually increase the salinity over days.

If salinity and ammonia are not the issue then it points to a parasite. Velvet can kill very quickly. Problem is if it was a parasite adding more fish can just lead to more deaths unless you let the tank go fishless for 76 days. Then quarantine new purchases in the future.

Did you notice any red sores on these fish at all?

Uronema is a parasite that is likely to affect chromis. This parasite does not require a fish host so it could have already been present in your tank and then once the chromis were added the parasites afflicted the fish.
