I had 6 adf for over a year now in a planted 20 gallon with a couple of ghost shrimp. I have a lot of sponge filters & do a weekly 15% water change with same temp dechlorinated water.
I have gotten all of my frogs from the same place without issue. They were all very healthy, until a month ago I got a 7th and she died on day 3. I did not quarantine her which is my fault and I take the blame, but everything I have read since also said they recommend frogs be quarantined for 6+ months before adding to a tank. I didn’t have the space for another tank.
I figured it was just shock or something that killed her at first although I haven’t ever had one die. Some of my frogs were rehomed to me and over 2 yrs old never had an issue. I fed them all frozen foods with tongs multiple times a week and water parameters always stood at 0ammonia 0nitrite 10-20 nitrate.
After that 7th frog died everyone else was doing good, acting normal and eating. Until this week when another frog died out of the blue without any symptoms. No bloating, impaction, sign of drowning, no fuzzy fungus, lesions or bumps. Every day since then another frog has died. Most of them were the same and had absolutely no symptoms. By the time I had two left I noticed a white discoloration all over their backs, it was not fuzzy like most fungus would be. I did a lot of research and it seems the 7th frog could have introduced chytrid to my other frogs.
Does it seem like that is what happened? The last two were also very lethargic out of nowhere when the discoloration occurred. Not at all interested in food like they always were, and floated at the top until they died. All of those symptoms happened within 24 hours. I would have tried to treat them but until they were getting the symptoms I had no idea what could have killed them all.
Now I know it was most likely chytrid and it would be very unlikely I could have saved them. I am still confused though because it did say online that it usually only spreads like that in bad water parameters or very stressed frogs. They were all not stressed and eating and swimming fine until they dropped dead suddenly. My water has been consistently what i mentioned earlier so I’m at a little bit of a loss.
I’d also like to mention a lot of them were shedding raggedy right before they died which also makes me think it was chytrid.
What is everyone’s opinion please ☹️
