You can't breed the axolotl using tropical fish items on Bedrock. You can only breed them using a bucket of tropical fish. This isn't in parity with Java, where you can breed them with tropical fish items, alongside Bucket of Tropical Fish.
Step to Reproduce
1. Spawn a couple of axolotls
2. Breed them with tropical fish items
---> ❌ You can't.
Thank you for your report!
However, this issue is Working as Intended.
The report you have submitted is working as intended: Axolotls can only be bred with a Bucket of Tropical Fish because axolotls IRL only eat live fish.
Please note, that mechanics of the game may change between updates.
Things such as graphics, sounds, world creation, biomes, redstone, villagers, and animals may not work the same in current versions.
