Recently on my golden axie I noticed what looks exactly like a transparent fish egg on the end of one of it's gills. It hasnt eaten in about a week now which i originally attributed to rapidly changing temperatures but my albino axolotl in another tank setup is now eating a healthy amount after being kept at a consistently low temperature. I only just noticed the egg thing on the end of the gill due to it being transparent but this is definitely a cause for concern! The growth itself is totally round and see through and about 5mm wide. I haven't heard of anything like this before it is really worrying me as I have had this axolotl for 7 years now, it's at least 10 years old and I haven't seen it in such a poor state before, although it did lose an arm half a year ago
