Replace spotted cory?

[mooman]

I iontroduced all of my fish putting the bag in the tank for 30 or so minutes to equalize temp and then transferring by net.

You probably just forgot to say this, but you did slowly add tank water a little at a time until you had doubled the volume in the bag right?

Here's how I introduce all my fish now, I had to get some hardware for it, but have not lost a fish to transfer shock since.

1. small bucket (got mine in paint section of Lowe's, it even has measurement lines for double duty, I use it only for tank use!)
2. Airline tubing
3. a valve so you can control flow.

put the fish in the bucket
start siphoning tank water and then turn down the valve untll you get a drip or two every second. Fill the bucket and dump in fish. The temp will remain stable (water has a very high specific heat) for the time it takes to fill bucket.

This way both the temp and water chemistry change slowly and constantly over time.

You're right that I forgot a step. I wasn't quite as careful about it as you are, but I actually let the bag float in the tank for 20-30 minutes, adding some tank water and let it float some more, then added the fish.

peppered corys and spotted corys are different. I thought they both grew around 2.5'' to 3''...

You're right - my bad.

Nice looking cory!

You can have about 4 to 5 corys is an eclipse 12 ( I do) Its not over crowded though the more fish you have, more waste is produced, thus the more water changes you should make. I would definitely get at least 2 more corys as they are Shoaling fish and act more normal with friends!
Also the other fish you have are respectivly mid level and top level swimming fish thus they occupy different areas of the tank than the corys. Thus they are not crowding it.
Hope this helps

I'm not quite as careful as mooman, but what I do is let the bag float for about 20 minutes, then I dump the bag and water into a large bucket, pitcher, whatever. Then over the next hour or two depending on what the fish is I add tank water every 10 minutes or so, a little at a time, until it is about 75% tank water and 25% store water, then I net the fish and put it in the tank. I've always had very good luck with that method, fish don't seem stressed much at all once I add them to the tank.
