Hi TommyBoi! Thanks for your help. I saw your message earlier and went to my local fish shop to buy another air pump ready to separate them, but they'd sold out of air pumps and connectors. Typical! I've ordered one online so hopefully it will come tomorrow and I'll be able to separate them. Today I have 4 tadpoles that look like the one in the photos above, and about 10 that have all four limbs but large heads. Most of the others just have back legs. The one in the photos above is absorbing his tail now as it's a little bit shorter, he's no longer using it at all, and the tail has lost all of that clear tissue that was surrounding it. Will a tadpole only start absorbing its tail (and stop eating) once the tail has stopped moving? It would be useful to know so I don't end up starving them or overfeeding them once all the tadpoles with 4 limbs are in their own tank. Thanks again for your advice
Xenopus Borealis and Muelleri are beautiful! Are you hoping to breed them?
