Recently, I purcahsed a Blue Gourami and a Gold Gourami. I thought they were both female but I could be wrong. They both shared a 20H witha common pleco. The gold took control of the tank and harrassed the blue until she hid and infected the tank with Ich. I moved her into a 10g hospital tank that I had set up earlier. I have never kept gouramis or aggressive fish, and the blue is still hiding and looking very sick in the hospital tank. She just sits at the bottom and her color is very pale. I have coppersafe in the hospital tank. She had a large chunk of her tail fin bit off as well. Any suggestions?
You could try a little Melafix, to help her regrow that fin (I've read conflicting info about treating Gourami with Melafix, I've done it, and had good results).
If you are certain the Gold Gourami is the aggressor, I wouldn't put them back together. If you do want to give it another go though, do this.
Take the gold Gourami Out
Rearrange the tank (Move the caves and such)
Introduce the Blue Gourami back into the tank FIRST (lets her claim a spot first)
Then put the gold one back in (I'd keep her the quarantine overnight, while the blue one adjusts)
This may not work, and you may very well end up returning one of the gourami.
As far as putting the blue gourami in quarantine....If she does indeed have Ich, then your 20H has it as well, you will need to address the Ich issue in that tank too.
A side note, That Common Pleco is going to outgrow that tank in no time (They get huge, I've heard up to 18" and more).
