Weaning takes a while . I tried on small anglers without success . They become too weak if not fed enough . They will literally refuse to eat even if they are starving . Then no matter what you do they won't eat . When I tried , I used small slivers of fish , shrimp on bamboo skewers and danced around them to no avail . Tried regular guppies and they would death spiral in the salt and not be available. Once the guppy is dead, the angler will never be enticed even if it floats by in the current. Some of the mail order bait suppliers in Florida also provide sailfin mollies raised in salt along with the SW killifish if you need something larger in size and bulk quantity . I never wanted to spend the money on pet store mollies at $3 ea for a one time meal . The breeding attempt of mollies is also slow, either slow growing to size or slow in production . I also had a really large angler that was so fearless and always hungry that anything that moved dead or alive was fair game , even my fingers when I would clean the tank. So my advice is not to rush the weaning .
