I started a 10 gallon tank in January with two Dwarf Gourami's, one flame called Sweet Potato and one blue neon called Cookie (my 3 year old named them). Sweet Potato is larger. I asked at the store if this would be a problem, they said it would be fine. It's not. From the beginning, Sweet Potato has been picking on Cookie and chasing him all over the tank. At first this wasn't so bad since Cookie had a hide out in a little Shrine, too small for Sweet Potato. But since then, we have added a bottom feeder who has decided to claim this Shrine as his home and often tries to kick Cookie out. Sweet Potato has also recently discovered he can fit in there as well. In the past week or so Cookie just seems miserable. He hasn't been going to the top to eat like he used too. He doesn't really show any interest in food. He looks a little dull and part of his back fin is bent. He definitely is not as happy as he was. We have tested for Ammonia and PH, both are perfect. We feed them flakes every two days. We don't have a nitrate test kit (yet). We have one plastic plant, one Shrine and one other rock type thingy they can swim through. Temp is around 75. What could be wrong with Cookie?? I am just waiting to find floating on the top one morning. I thought of buying another Gourami, to try and even the score. But should I go with another Flame or another smaller Blue Neon or another Gourami altogether? Or do I try and introduce a female? I am not interested in breeding however, so this makes me nervous. What to do!!
