Hey guys well I was playing with some ideas in my head and I thought of one and the more I thought about it the more interested I was. I was thinking about a ropefish tank only type set-up. I'm wondering what size tank would be good for 3-5 of them and maybe what the dimensions might be. I have a 75g right now that could be used, but I thought that maybe a 120 (4x2x2) would be better. However if I can't get a 120 with those dimensions how many ropes can I have in my 75? Thanks
