A couple of my female guppies have grown quite a bit. Their stomaches look quite large. That silver belly is very prevalent. I havent noticed any dark gravid spot. They eat well and swim very happily. They are quite agressive towards my bottom feeders when it comes to food. They are very competitive!!! No sign of dropsy, scales look good at all angles. I change water once or twice per week. No sign of lethargy. Very eager to see me LOL
