Possible bloat--Salamandra salamandra

I recently noticed that one of my fire salamanders is abnormally fat, despite having not fed much in the past several days.
This image is better quality:

But this one shows the issue better, I think:

I thought of three possibilities for what this could be: a gravid female, bloat, or impaction. However, I suspect that this salamander is male because the cloaca sticks out and it did so before I noticed this issue. This salamander has not fed for several days, so I don't think it's merely fat. It has been fed exclusively on calcium dusted crickets for the past several months, and I have read that overfeeding insects can cause impaction. However, I do not know how to differentiate between impaction and bloat. Does anybody have any suggestions? I know you can treat bloat at least temporarily by putting the animal in a salt bath, but I do not want to unnecessarily subject my salamander to this stress.
This has not been going on very long (two or three weeks at most), if that is helpful.

It doesn't look like bloat to me, and i doubt feeding crickets would cause impaction, though i would recommend feeding worms more often for a variation in diet and more nutritional value.

He looks perfectly fine to me. Maybe there were some leftover crickets in the tank that he ate? I wouldn't be too concerned

I’ve seen bloat in Salamandra and the animal looked like it had been blown up so much it’d surely pop. Not just the lower abdomen but the entire body. I thought it would die as it couldn’t move. After six weeks or more it recovered. Lesson learned.This I suspect was due to feeding too many crickets in the winter during periods of activity and hibernation. I think this can happen with all chitinous inverts. If I could, I’d feed earthworms and slugs but a) crickets are convenient and easily dusted with Ca and b) my garden is all wormed and slugged out. Your animal looks ok to me.

Glad to hear you both think he looks normal. He's now much skinnier, and I think it must have just been food taking longer to pass after all.

I don't know about slugs, but earthworms have an essentially perfect calcium:phosphorous ratio for vertebrates, as far as I know. I bet slugs are better than crickets, just because of their shelled ancestry, but I've never seen any numbers for them.

I feed mine nearly exclusively on crickets and I've never had a problem. It looks like it might be impacted. Try keeping it on moist paper towels for a few weeks and offer it earthworms. Maybe it will pass the obstruction. I don't think the body shape matches being gravid.

Good to know you've never had an issue with crickets. He's looking normal now. I think whatever the issue was, if there was one, has passed. I'll keep in mind the paper towel advice for the future, though.

Good to hear! What's the make up of your breeding group?

At the moment, just 1 male, 1 female. They're siblings, so at some point I'll probably be looking to trade in order to increase genetic diversity. I figure with fire salamander lifespans, though, I don't need to rush. I'm not going to try breeding this year--I absolutely wasn't prepared, since I thought they were both female--but next year is on the table, particularly if I can avoid breeding siblings then.
I don't think I have space for more than one male and one female in the foreseeable future, but I guess we will see. It would be nice to have more adults if I were trying to breed.

I personally wouldn't worry too much about a generation of inbreeding. And there aren't many of these available any more in the US due to the ban.

Probably a bit late to respond since it seems to have gone away, but just in case it happens again - 1 of my newts (different species) had bloat and as Blackbun said above it looks like they should have burst a long time ago when they have it. For mine it seemed to develop very quickly, although it didn't seem to affect her appetite or movement really (mine are aquatic newts, so probably would affect terrestrial movement...). Wish I could find the photo I took....

    i highly recommend “buyanaxolotl.com”- ive purchased from them and received a beautiful animal for relatively cheap, in great condition, and excellent shipping precautions. the breeders are a couple living in georgia (i believe, don’t quite remember) and they’re fantastic. sometimes their website contact page doesn’t work, so i’d probably try just emailing them. good luck and happy hunting!

    Hi all I'm new here I'm just looking some advise on cycle witch is currently driving me insane . So we are week 8 I'm dosing daily with 4pp of amonia and for the last week has been dropping to zero witch I no is good. But my question is my nitrites are sitting at between 0.50 and 1.0 PM and nitrates are between 10 and 20 and neither of these seem to be dropping. I have done 2 40% water changes a few days ago and no change the only thing I can think of is I didnt use the seachem stability stuff which I have now ordered but surely that shouldn't have much difference this far into cycling

  • ytz13513:
    Dropping ammonia with rising nitrate and nitrite is good. It means the nitrifying bacteria is working. You just have to remove the nitrate from the water doing water changes. The level of nitrates is high and the nitrate is also high. The nitrite will be converted to nitrate using the beneficial bacteria and you can add them using quick start or allowing them to naturally grow in the tank. The latter option will take longer. The nitrate can be used by plants, so live plants can decrease the levels, but I would do a water change to get the nitrate at a level that is lower than 5 ppm. 5ppm of nitrate is natural and a good place.

    New here. hope this is the right place to post my question. I had 27 axolotyls aged 2-3 months old. main food has been finely chopped up bloodworms. no problems. I decided to introduce earthworms from my earthworm compost bin for variety. I finely chopped up 4 small earthworms and fed them to the babies. Within an hour 20 of the babies were dead. The remaining 7 (the smaller babies) survived and are now fine on bloodworms. Any ideas why the chopped up earthworms killed many of the babies?
