The year before last, about a block away from my house, I found some tadpoles in a small roadside drainage catch with no outlet. It was about to dry up, with no rain in sight (I live on a lava butte in the desert. The road ditch was new, I think it was the first time the local frogs had laid there) so I caught as many as I could and relocated them to a slow part of the local river with reeds. I kept 6 and I dunno, I just wanted to post pictures. They're so cute and I had so much fun building them homes. :D
They stayed in my old aquarium until they sprouted legs (an old practice of mine since I was a little kid) :p
Then I built this: 10 gallons, with 1 gallon of water and a functioning waterfall that dripped down and made the "cave" moist. I used glass from a picture frame and toped it off with sealant and rocks. I had a female betta in the water to eat the tiny crickets that fell in. I later removed her as the cricket load got higher. Crickets are so dumb, even if you give them a way out of the water they choose to drown X( It also had a better sound, and lost less water, if I let the water level drop over an inch from the rim.
My plan was always to let them go back into the wild, as soon as it got warm again, but I also wanted to keep them around... :3 Soooo... of course there was only one practical choice: Build a pond for them XD I did it once the weather started to get nice last year.
Start to finish: My yard was pretty bare, hard sand filled with lava rocks. The rocks I pulled out of the hole helped make the area (pictured below) level. All the lava rocks you see here came from the small 75 gallon hole... I even broke a pick axe :o It was so worth it though. I also have pretty deep rock over-hangs going on the edges and it really helps keep evaporation down. I barely loose any water. :D
The plants around the pond look so awesome and full this year, but a raccoon pulled a lot of the rocks in right before it froze last winter, so I have to redo that part before I take more pictures ;p But I can hear 2 of the little frogs croaking right now :3 Yayness :) I'm so happy
