Because of Octo's compulsive tailbiting, I moved him back in his 3gal, even though space on my little desk is starting to get cramped. His 3gal has a combination of glass stones and sand for substrate. I have a tall silk plant, his shark cave, a styrofoam cup, his heater and filter in there.
Hestia's tank is still the same, but I rearranged things in there to add a new toy (Octo has the same toy in his tank). I actually found it at Toys R Us for 5 bucks each and washed them well (no soap!) to remove any icky germs from kids/parents/babies. The toy is for babies years 0 and up, hahah.
I got this idea from a picture that another user posted. In it, the OP was asking about where they could find this. I was looking for it earlier, but as I just woke up, I have no patience to figure out who the OP is so I could let them know.

They LOVE the toy! Hestia likes to bask in it, and when I try to take a picture of her in the ball, she swims out and glares at me. Octo, well... When I first put the toy in his tank and released him, he spent a good five minutes flaring at it and wouldn't go in it for a day. Now he uses it as a shortcut to get to the other side faster.
Hestia's setup. She never really likes to be out in the open, and prefers scavenging through her plant and toys.
Whatchoo dong, Mom?
Octo's setup - sorry for the quality. The water really is clear, but the tank is slightly discolored.
