If you so desire, place a couple of floating plants at the corners. They love to pick out out a corner under some plants to call their own. You might even catch some of them making a bubble nest amongst the floating plants.
Wow! I knew that they had labyrinth organs but I thought only bettas made bubble nests. That's cool! But it seems that they're figuring out pecking order. I did break up a fight earlier (just circling and biting the tails) Only one I've seen, but of course that means they've had more. But for now they seem to have divided up the big clump of plants in the corner. One is way at the bottom in near the gravel, one is in the middle in the back, and one (the bully) seems to be in the other plants. They all come out and swim and everything, but they seem to always go back to the same place in the plants. Kinda worried about the bully, but if push comes to shove I know that I could take him back and exchange him for another (hopefully less agressive) of the same species. That's the joy of buying from the mom and pop fish stores, much more understanding than Petsmart.
But for now, they all have all their fins, no real damage to each other, look healthy, swim great, and are eating.
I think they're so pretty! My fiancee didn't care what kind I got as long as the tank had color, and i thought dwarf gouramis were perfect! Now just waiting on the assassin snail shipment (should be here wednesday) for my other tank, and I'll be happy as can be! Oh, and a great thing I saw was the one gourami eating the big algae off the plants (you know the stringy weird almost thick mossy looking kind). I was so excited to see that! My oto won't go near the stuff.
