sorry if I came out like a dick, not trying to be mean. just trying to point this out to you.
you came here asking for expert opinions without bias. There have been several answers telling you to stick with a small goby, but you prefer the LFS's opinions. LFS is trying to make money off of you, we are not.. then you defend them with more retailer's opinions. so then why ask here in the first place?
this isn't your first tank and you seem to have been in the scene for awhile. You should know all about cycling and what it does to your clown. why hurt your pet. This is like a human living in a closet filled with smoke. Going to be a tough life.
How did your tang do in your 50gal in 2012. You are in the same situation again.
