Was finally able to pick up some shrimp to try and feed my 2 gulpers iv had for about 2 weeks. Ik they topically don't eat until a month after getting them but how do you guys get them to start eating? I was able to get one to bite the shrimp but he just let go. Do I leave the shrimp in the tank? How long? I was using tongs but really no luck and when they came out I tried hand feeding and still no luck. How long do I wait until I just use feeders? I have a 20L I guess I could breed feeders but I'd rather use shrimp. Maybe live shrimp? But I think that'll be to small or to expensive
