He/she will be in this tank for at least three more weeks, while the bigger tank is cycling.
It moved away from the heater a little bit, and I checked a couple of times at night, when all the lights were off and it seems to explore the whole tank at night.
I have given it algae wafers and it ignores those absolutely completely. But, because there currently is guppy fry in the tank as well, we feed very small crumbled flakes twice a day, so I am guessing it eats some of those too while hovering the gravel??
Someone said I could feed it a piece of cucumber without the seeds, but I will have to buy a clip first (PetSmart only sold these hideous Nemo shaped clips...)
It seems happy enough, and it is very peaceful, it even leaves the plants alone...
