Here are my females...



And here is my newest male...




See how my male has more vibrant colours and longer, free-flowing fins? Please, PLEASE, do not put them in the same tank. The smaller may be a female as well, mine are quite small. As well, do you see a little bulge under the little fins in front? It is an egg sac, thats a female. Also, the 2 fins in front, are SMALLER on females while again, the males are MUCH longer and pull underneath him while he swims. Females do not flare as much as the males and have smaller gills...
