Please help! Chytrid in ADF??

Hi there,

I have two ADFs purchased in early October 2020. Over the past few days one of them has gotten slightly lighter in color and has a red spot on its nose. Internet digging had me thinking it was just a bruise but now the frog is floating at the top of the tank, sticking its nose out pretty much all day for the past couple days, sometimes scrabbling like it’s trying to get out but mostly just floating. It’s also got some skin shedding off its nose and hasn’t been eating. All the symptoms seem to point at chytrid but if I’ve had them for over 2 months it can’t be that, can it? I appreciate any help!

 

I don't see why chytrid would have to manifest immediately.

 

I guess I’d read that they would die of it within 2 months if they had the fungus? And since we’ve had them for over 3 months and nothing new has been introduced to their tank (aside from water) I didn’t think they could catch. This is all new to me though, I could be wrong! It doesn’t seem like the symptoms fit other bacterial or fungal infections though
*catch it

 

They're not guaranteed to develop an infection the moment they're exposed to it. I wouldn't rule out chytrid on that basis.

 

Good to know, thank you! I’ve been trying to wade through treatment options and it seems like a lamisil bath may be the way to go? Any tips for that if so? We have two in the same tank so I’m guessing I should treat both and quarantine?

I know it was a big deal a few years ago so I'm sure there are a whole bunch of scientific papers by now. But I don't have amphibians so I haven't read any of the papers.

Do people just use the Lamisil they sell for athlete's foot and stuff? That's the only version I'm aware of that doesn't need a prescription.

 

Hi welcome to FishLore
Chytrid can take months to show symptoms (that's why it's recommended to quarantine any new frogs for 2-3 months)

Have you tested your water? Shedding, floating, not eating can also point to bad water conditions, something leaching toxins (a decoration that is not aquarium safe).
The red spot may be bacterial or an injury.

A little more info abut your tank and it's inhabitants might be helpful. I've never had to do Lamisil treatments but do a forum search several have.

 

Red nose is very common in frogs rubbing to try and escape. Either a filter screen or mesh lid or something abrasive. Once injured infections are common.

Lucy is right the most likely culprit is dirty water that has caused systemic infection via the nose injury.

While chytrid can appear later it is usually very fast acting in susceptible frogs so I would not expect it to appear after many months after without changes having been made.

Consider also (I'm sure not in this case) that frogs can live with chytrid and it can then develop to disease with a change in conditions. Example: warm water may alter the interaction in the frogs favour but a seasonal shift or broken heater might cause the balance to reverse and the frog to become I'll.
