If not for bad luck...

Found the info I needed about substrate and rock in the tank. Not the best idea, so that tank would not be the greatest to use either. Will be costly in water changes also to keep ammonia down.

Lights just came on and fish are now showing some signs. No spots that i can see, but rubbing on stuff and alittle breathing heavier. Not sure i can get them all out, but will try. Chances are that everything will be dead soon. Sad this is a brand new tank and these were the 1st additions. Always learning more in this hobby, good and bad. No matter how long you have been in the hobby.

Adding copper to an aquarium with substrate is definitely NOT a good idea. Part of the problem is that many substrates absorb copper and medications so controlling the proper copper concentration is a lost cause.

QTs need to be bare bottom unless the fish itself needs to burrow. All connecting apparatus needs to be discarded or replaced. The tank should be cleaned and allowed to completely dry before using as a QT.

Buy bottled bacteria to kick off the bacteria cycle.

Amyloodinium ocellatum (Marine Velvet) has been known to infect the gills of fish. This is out of your sight. A fish flashing (rubbing itself against substrate or other things) mostly indicates a problem with it gills.
