I have a two tanks...I just had to separate my three sparkling gouramis from one because I didn't realize they'd kill shrimp that are the same size they are LOL. So they are in jail right now and I'm wanting to put them in my other tank. The other tank has two female platies and two cory cats in it. Its a 15 gallon tall with lots of branches and moss growing in it...would the platies pick on the sparkling gouramis? If so, I might see if I can take them back to the pet store. I really like the gouramis and would rather keep them.
