Heheheh! Stripes and Marge do this sort of thing on a regular basis, so in some ways I was kind of prepared - although this is the first time he has been
completely upside down, so I did have to go and check.....and guess what, he turned back over at a leisurely pace and waggled his fins in glee. Then he went back to doing it again once I sat back down.
He was resting in the dark shadows at the back of the tank in between some bogwood, hence the darkness of the pics. However he was in a substantial gap and was not resting against anything. I actually had to wonder if his dorsal fin was erect at the time, anchoring him in the sand?!
