Fish died when I was watching

[Nicksaquatics]

I opened the light this morning. My Kamohara blenny I got 2 days old, woke up and was swimming. 2 minutes later, as I was watching, it started floating upside down.

I tried to give it food but did not accept. He was my first fish. My tank has been cycling for about 6 weeks. I have a hammer coral and green star polyp and they look happy.

How can my fish die all of a sudden? He had all his colours then turned more white.

What action did you take to clean your tank after the oil got in it? In the ocean, oil spills kill a lot of marine life. I didn't see where you followed up on that thread. It appears that the blenny has been struggling since you got him. Did you quarantine or did he go straight into the display?

I did a 80% water change, then 50% the next day just to be sure. Nothing in my tank has oil in it. Contacted Fluval and all parts use electromagnetic drive system. Have not seen the oil since. He was acclimating for about 2 hours and yes he did go straight into the display, he was my first fish.

So sorry that your fish died. If it were my tank and I thought oil had been introduced, I would run high grade carbon or a poly-filter to remove any residual oil that might have stuck to surfaces. Just to be sure.

Even if it was your first fish, it's so important to quarantine so that you can identify any unusual behavior or appearance and treat accordingly. It's also an opportunity to get a fish to eat before he goes into the big tank.

I know you're disappointed, but buying sick fish happens. You really need a small quarantine tank before buying any more fish to give them and yourself a better chance to succeed. Good luck.

I went back to the fish store and they said the fish had just been acclimated to their tank when they sold it to me. They say it probably died of shock of changing aquariums so much in a short amount of time
