Jen Williams gifted me an 8.1 gallon Fluval all glass cube with glass lid. Gift was missing the lid clips to hold the glass lid. Glass is 3/16" or 3mm. The smallest lid clips I found on the internet are 6mm. I have a Dennerle Nanao all glass tank from the GWAPA workshop (that is in service as a small shrimp tank). Those are the perfect size. If you have any Dennerle Nano clips or something similar in size available that you are willing to part with I'm more than happy to pay a more than fair price plus shipping.
