Iv'e noticed with one of my tiger barbs that its stomach is really large....larger tha n normal (as far as i am aware it is a female) one of the other tiger barbs has a greenish tint to it and is pointing its nose downwards. He has been doing this for the last couple of days now but iv'e just notice the size of her today. Could she be carrying egss and if so what should i be doing? Whats happening with the other Green tininted barb?
