[Dwarf Gourami acts fine, looks TERRIBLE.]

I've had him about 9 months.  Purchased him with two others, and they are doing fine in the main tank.  It looks totally painful, but he's not acting like he is in any pain at all.  I cannot imagine he survives this, but as long as he does not look like he's suffering, I'll keep treating.  Thanks!

I should add, no new fish have been added to the tank in several months.  About a month ago, I added a few plants.

A few days ago, I noticed he was getting bloated, and the bloated area had turned white.  I moved him to a 10 gallon sick tank, increased the temp to 80, added some salt, and started treating with Melafix.

After a day, it looked a little worse.  Then, this morning (two days later) he is being destroyed by it.   I don't know what to make of it.  Funny thing is, he is not bothered by this - swimming normally, even eating (although I have greatly reduced food for him).  Any ideas what this may be?  Is this possibly sheading this bad area and healing on the inside?  Or, is it pretty much lights-out for the little guy?

Thanks everyone!   🙂  It's nice to finally identify them.

Sorry.  This should work now.

I picked up 4 of these little guys at a big-box store, and they did not know what they were.  Then, at Petco, I found just 1 of them.  They too did not know!  I've ruled out Bleeding Heart Tetras.  Any ideas?  Note the block spots on the top fin on some, but not others. 

They are a great fish.  Lot's of fun.  Thanks!
