POPULATION: ||| LA POPULATION :

3 Cyprinus carpio "Koi": 1 Shiro Utsuri, 2 Yamabuki Hariwake
2 Trachemys scripta elegans (Red Eared Slider)

Also 3 gold fish, a Trichogaster trichopterus, and a Gambusia affinis that are meant for food for those turtles.. it's funny that the turtles discriminate my comets goldfish rather than eat those small goldfish..

Picture of the current population: ||| Photo de la population actuelle :
2 of my Red eared sliders with koi's eggs on it's carapace..

Spoiler:

One of them got fungal infection in the head but it's getting better and the other got a blister in the head because she likes to play below the slider which still got hard cement on it..
The two of them aren't habitual with their environment yet, they haven't explored and basking in the land a lot..
