Riding the angler does not require a saddle, as soon as you tame it you can start farming silica. Also these creatures have a max torpor of about 700-900 so they do not take many narcotics/tranq arrows to tame.
If you build a base on the rock island in the lake in aberration or the big lake near the surface entrance breed an army of fully mutated anglers, mantas, and eels and set them on wander and aggressive and your lakes will be karkinos and spino free
- Main use is after tamed they will attract more anglers which can be harvest for gel
- Secondary use would be a mobile underwater tame that also has a built in light
- Lastly they can be harvested for gel which tames Manta's
(Angeler gel is the longest burning fuel source at 6 min per gel)
