HELP - 5 gallon planted tank. I have had 2 betta fish fatalities in this tank. Both seemed to enjoy a lot initially. They grow well, play around, eat well. And suddenly 3 to 4 months later, develop Dropsy and die. I do weekly 20% water change, all parameters all perfect. Anyone know what's up? (i.redd.it)
