Can mollies, mono argenteus, archer fish, a dragon goby and fiddler crabs all live together peacefully? and if so has anyone had any experience with all this fish together? my plans are to have 12 mollies (plus any babies that live), 4-6 archers, 3 monos (unless i need more, and if i would please tell me how many), 1 dragon goby and 2 fiddler crabs. tank size is not an issue, i currently have an 80gallon but i have a 150gallon on its way. i plan on building a hood for the tank with acrylic doors so the archer can spit at food. also i plan on adding a land area at the top of the water for the fiddler crabs. any input on all of this would be great. and even better if you have done something similar yourself.
