Unknown cause of fish death/autopsy requests

[carlson]

To start off, Ill say that I'm sure this wasn't ich or velvet, because I've had ich and velvet before and the fish haven't shown any signs of it. I bought three blue green chromis and these were the only three fish I made the mistake of not quarintining. I have three other fish, an older marron clown, a coris wrasse, and a yellow tang. My blue green chromis started disappearing one by one but I did find them all before the bodies began to decompose. I'm left to believe this was from some type of internal parasite, or unseen tank aggression. I caught the last one as I found it hiding in a rock and breathing rapidly, so I put it in the sump to see if maybe it was just aggression, and it was dead the next day. I've included pics of the last blue green chromis that died today, as well as a video of my other fish. I ask that anyone who watches the video please look at my fish carefully and let me know if they seem to have any problems. The yellow tang is still kind of pail, but it get more yellow every day. The fish store I got it from never fed it algae so when I got it it was very Pale, you couldn't even see yellow pigment on its tail, but ever since I got it I've fed it seaweed every day so far and it eats like a pig! Please please help me of you can I don't want to have any problems with the other fish. I'm going to start feeding the marine new life spectrum tomorrow to try and give them some extra immune support. Rn the other fish eat Sera Marlin pellet food and mysis shrimp.

Curious, did you get them from the same lfs? I'm wondering if they're improperly feeding them... if at all. I once bought some clowns that were very young. They didn't have the fat reserves to handle being transported to the lsf. I bought them the day after and lost them the day after that. The stress just got to them... Lesson learned. I make sure the fish I bring home are eating well before I buy them... I don't know if this is what happened to your chromis, but if you're saying your yellow tang is having issues due to improper nutrition from the lfs, and if you just bought these poor guys, it very well could be that they died due to stress brought about by poor nutrition. Just my $.02 worth... Raymond

Yeah... That yellow tang's been bleached! Poor fella. Raymond

That would be a relief if that was the cause, I'm just worried they they could have some type of parasite, but after I got them they were eating like pigs so I don't know. I had them for a week too before they died. My yellow tang has come a long ways since I got it though from not knowing what to do with seaweed to destroying sheets of it

Your clownfish seems to be fighting the current, migjt be suspect of parasites. But the other two look happy.

I had a chromis choke on a pellet before.. did you soak the pellets before feeding?

Did it die from that?

 

[amazongb]

Did it die from that?

Yes, and very quickly.. Now I feed the smaller fish flakes, or mysis..

I have also had a clown fish die from eating a sera marin pellet before, but the chromis were eating frozen food. I didn't really pay attention to whether or not they were eating
