Abe spent lots of time on land for his missions. With a hydration suit on to support his sensitive skin, eyes and gills so he wouldn't dry out but he spent all day out of his home of the water.
So understandably pretty much the moment you all got back to base he was stripping off his hydration gear for the real thing slipping into his large tank without a splash or even a ripple.
But as comfortable as the tank was, he would still get a little bored. Abe loved to listen to classical music and love songs through his tank, liked to swim laps, nap and with your help read! He appreciated when people would flip position his books for him in front of his tank and flip the pages for him but that was a slow process...you were better.
He gently places his hands on the glass, staring at you in his tank through the barrier as you sit on the other side. He smiles, his big glossy black eyes looking at you lovingly. "Would it be too much trouble for you to read something out loud for me, dearest? Might be less tedious if you'd be so willing..." He says softly through the water.
