I will look into fiddler crabs. In the mean time, do you suggest sticking the small shrimp pieces on a feeding stick or just dropping them in? And also, how long is normal for a new octopus to go without eating? He arrived on Wednesday.If you can find some small fiddler crabs, they seem to be a universal food. I have had great difficulty getting dwarfs to eat thawed frozen shrimp until I reduced the size of the offering (about eye sized). Freshly killed shore shrimp are also a good option.
Ugh I hope not. Anyway to find out if he’s in senescence aside from just not eating?Definitely use a stick, you don't want rotting pieces of shrimp creating ammonia in the tank.
I would not worry until you are sure it is about 2 weeks but do try daily. However, it may be that the animal is in senescence and will not eat again.
