Afan Dwarf Frog with missing foot (possible fungus)- advice needed please

[tgampper]

The tank is cycled, and all the levels are fine.

That's great! Proper water chemistry is vital to the good health of your frogs. Healthy frogs are remarkable in the way the fight off disease - their skin contains the chemical magainin, an antimicrobial that protects the frog from a variety of bacterial and fungal infections.

I gave him some bloodworms last night and he ate a few, not loads, but then I guess he's really small.

The frog is probably under stress which will go away over time. It looks like its had a rough time. As long as it is eating, you shouldn't worry too much. Keep the frog in a quiet area.

I haven't seen him at the surface at all, in fact I'm a bit worried that he's not surfacing enough (how often should they surface for air?)

They can stay underwater for a long time. The frog is an agile swimmer - and can move quickly both forward and backward. As long as the frog swims naturally, I wouldn't worry. Continue to observe as often as possible. If there is anything unusual, please note it and post on this thread.
