I kept him in small plastic tank containing water , and used to feed .My mom kinda freaked out when she saw it first , then eventually she started to love him , she was the one who feed him , changes the water for him and so , and surprisingly my dad and grandfather did too.
But as we all know good things must come to and end , i found him dead in his tank yesterday , he wasn't moving , it was really sad , i actually miss the green little fellow , he wasn't as annoying and demanding as most pets are . Anyway R.I.P. Poseidon , you shall be missed .
