I have a 37 gallon fowlr tank and recently purchased an Octopus 1000 skimmer. I have no sump, so the heater,filter, skimmer and UV are all in the back of the tank. The problem is, I have already ordered a diamond goby that will be arriving in a few weeks. What are my options for a lid? Is there a place that can make a custom lid that you can recommend?
