I work at Captain Nemo's in PA. I get in and clean that tank every couple of months, when the spots on the glass get to where I can't remove them working from outside. We just shot a commercial so it had to look its best. Anyone interested in employment should send a current resume with a recent swimsuit pic!
To be honest our dry goods prices can't compete with TFP, but it's worth checking out the livestock if you're in the area. I run the service and maintenance end of the business, but I consult a bit on ordering the livestock and I can pretty much guarantee that you'll see some unusual stuff in both FW and SW.
