I was looking at the posted sizes and it says your angler is 1.5" and the toad is 4.5" if that is correct the angler will probably become dinner at some point. Hope not but it is a distinct possibility. Get a clear acrylic rod and use it to feed thawed krill to both the toad and angler this is how I fed my angler after a while I was feeding him cubes of formula 2 (i think thats right) with the rod he loved it, no more worring about the ability to get feeders. Also becarful with feeding fresh water feeders to them. Its kinda like feeding brine shrimp all the time with the added threat of infection. One more bit of knowledge before I go ( i found this out the hard way) dont let the angler ingest air, keep them submersed at all times. If they ingest air they can not expel it and will bloat and die.
Two really incredible fish I hope they do well for you. Good luck.
