Beautiful axies! I do have to warn you though, the tankmates might prove to be a problem soon!
The fish obviously aren't a problem because your axies have lovely gills, but the pleco and dojo loach could be problematic.
I'm surprised you still have the loach, to be honest. At his current size he can still fit in their mouths. You will probably end up with a dead loach, or a dead axie (it wouldn't be able to swallow it). Now, if he makes it to a larger size, the axies won't pose a threat to him anymore, but as far as I know, dojo loaches get REALLY big and will need a larger tank.
The plec is dangerous because they tend to have a taste for axolotl slime coat. There have been plenty of very sad cases here on the forum where someone put a plec with an axolotl and the plec decided to suck on the poor axie. This tends to end in severe skin damage to the point of the skin coming off all together! Very very painful looking and results in a dead axie.
Perhaps consider changing up their housing so that all your critters are safe?
