Glass Cardinal - Problems?

[GoFish]

And seeing as how more interest has been given to "Scribbles" (Rabbitfish) here's a pic too.
If he could talk I'm sure he'd be stoked people are talking about him...the supermodel of my tank... (and a PHOTOBOMBER!)
Have had him for 8 months, Started out 2.5" long, and is now a whopping 3" long... If he gets too big for the tank i'll either sell him or buy a bigger tank, no big deal, he says thanks for the concern!
