Got 2 females that I bought with sunken bellies, my mistake didn't inspect properly before purchase from private seller for 1 and the other got given to me with the purchase of some healthy ones. Been trying to get them back into condition but don't seem to be having any luck. Would really like to get them back into survival contention the picture is of the worst one the other being about 50% of the sunken belly. If you guys have a process or any tips I should try that would be great hate losing a fry here and there let alone big girls like these. Had these fish for 4 & 6 weeks now.
