I have a 20 gallon with 1 dwarf gourami, 2 honey gouramis, 5 cherry barbs, 3 neon tetras, 1 kuhli loach, 1 False siamese algae eater, 5 panda cories, 1 singapore flower shrimp, and 3 wood shrimp. Would be able to add about 3 adfs without andy problems? I am only concerned about the shrimp bothering them but they keep to them selves and dont have pinchers.

I don't know about the Singapore flower shrimp but the ADF's should be fine with the other animals that you mentioned.

the flower shrimp is actually my smallest shrimp. he is about 1.3 in. He is the same as the wood shrimp but smaller and different color. The shrimp all act the same and are very peaceful around my other fish so i will probably get the adfs.

Thanks for your help Robyn. today i just added two adfs to my tank and nobody is bothering them! They were playing a leap frog kind of game with my school of 5 panda cories. I bought frozen blood worms.
