Ok so I have a 55
gal tank and I want to start adding some fish to it:p...but not sure which ones will eat the others. I want to get a Hammers Cobalt Lobster along with some red cherry shrimp AND freshwater clams. Will the Lobster eat the shrimp AND the clams

? I was also told if I get mystery snails the lobster will eat those..which is fine with me...cause Ive had those things multiply by the thousands

! My next question is what are the most colorful, peaceful freshwater fish? Basically confused and need some advice

....thanks in advance!
