Fish Deaths

[zeeter]

75gl tank
Population:
2 GSM's
2 Behn's Damselfish (jerks told me they were Chromis)
1 Lemon Tang
1 Pink Chromis
1 Royal Gamma
1 PJ Cardinal
1 Nox Angel

First of all, I know I'm overstocked and the first to go will be the damsels. I hate them. They were cute when I got them as "Yellow Striped Chromis" at the LFS. They got considerably larger than I expected and are quite aggressive.

That said, I have in recent months added a Watchman Goby which disappeared after a day or so. I also got a cleaner wrasse on Saturday which was gone by Sunday.

Water is fine; I recently added two tanks to the system and the fish in those tanks were unaffected by the water parameters, which nosedived when I added them because I used the old sand/crushed coral from their old systems. Stirring up that sand during transit let out a lot of bio-waste that fouled up the tanks for a few days. Yet the fish were fine. The main DT is very mature; good bio filtration, good skimmer, good mechanical.

So I'm leaning towards the Behns attacking newcomers. The GSM's and the Lemon Tang keep them in check, but they chase everything else around.

Any other suggestions?

way too many fish. fish kill fish, not guns. LOl but really take out a bunch and what is your params?

-Yellow Watchman- will burrow and hide underneath the sands. for months.. mine went mia for almost one year, then out of nowhere reared its ugly head.. much bigger and fatter.

-cleaner wrasse- tend to jump through the smallest cracks and holes, they also can hide for days if stressed and die due to starvation.

get rid of the damsels. and better luck catching them..

I'm meeting a guy today and giving him the damsels. I think they're the culprits. After that I think the tank will settle down. Seems all of the drama in there centers around the damsels. All of the other fish get along just fine.

I had the same thing happen with a cleaner wrasse in the past. I moved a rock one day and there he was just a little more than needle thin. He didn't make it after I quarantined him.
