Unfortunately, it was ascites that I got out of feedingLikely stress was the killer
I got guppies for feeding and they were ill.Ascites from over feeding over 4 years?
It's just poor genetics.What illness did the guppies have?
I have Buttikoferi in another tank. They have less than 20cm nowButtikoferi pair and a Labiatus pair….things aren’t going to end well.
