Yes it would be a 4 foot 55 gallon tank. I would prefer the one spot foxface over a tang if that’s do able and I mean I’m literally getting everything else for free besides the tank and lights. I’m getting a sump protein skimmer and wave makers for free plus live rock for free and an roi system for free don’t know where else the cost is coming into play? But yah just based on space the 55 works better for me. So if a one spot fox face would work for life in that tank that would be awesome.
