My 12 White Labs and 20 Demasoni just arrived today, they are settling in well in their new 75 gallon home. I requested that the order be mostly female, so to avoid too much aggression, but we'll see how everything goes. I'll try to post some pics of the tank and fish tomorrow.
Just an update. Everyone seems to be settling in well. Everyone's eating and not too much aggression. I can see some male Demasoni claiming their territory but not major issues. I have been feeding them Spirula flakes, spirula brineshrimp and Emerald Cusine. Here are some pics, hopefully I can get them to post.
