Mongo and big son Hugo. You can see Hugo's bulk in comparison. He actually 'striped up' for this picture. Normally he's pretty faded. His bars aren't as dark as brother Stripey though.
The bad brothers have a momentary truce. Scooter is in the background. As juveniles, Mongo was bigger. Slade is now larger as adults. Mongo is just over 4", Slade 4 1/2+".
Mote picks at the walls of the cave. Slade watches and Mongo takes his leave. The fish seem to like pecking at the foam and sand. Look closely and you'll see Dusty over the rocks.
