in my experience, those bigger bubble type yuma and hairy mushroom are quite hard to keep. Esp the bigger bubble yuma. Now got two pink and red yuma melting away.
Both yuma are in the system for about a month or so. There are ok until today. i have also melted another 3 red yuma before. Same way like these 2 yuma now. The rest of the yuma are ok.
IMO, I think the reason for melting is because of the ionic balance of the water. i ever recall i try changing water when i notice the yuma are stress. Only manage to save one out of 2. But its usually too late most of the time.
Any one knows what's actually causing the big bubble type yuma to melt??
