I am in possesion of both a 20 gallon long and a 29 gallon for a shrimp tank. I was wondering which you would feel would be better. It will be low light with anubias, moss, and sagetaria being the primary plants in this proposed setup. Which one do you feel would be better for breeding shrimp. I am planning on housing(and hopefully breeding) crystal red shrimp and red cherry shrimp.
