ok I am still in the process of fixing up a 20gal long aquarium its been at least a couple of months now and i haven't put any live stock in yet.. I can never choose what fish i want to keep or much more important then that its hard for me to come up with money as a college student. Pipefish are so cool.. does anyone know any readings i can read about them or good resources. also would they do good in a 20 gal long if it were FOWLR. I really need to find a job
