Hello all:
Out of the shadows I come from months of lurking. What an amazing forum! I'm hoping anyone interested can give me a quick reality check on my idea here...
TL/DR: Are my ideas below any good? How can I assemble a tiny, easy-to-clean, filtered drinking water dish for small tree frogs? The stagnant dish with its daily changes is no bueno.
I have a 20 tall terrarium hosting about 3 local Baja tree frogs (I'm in Southern California), and I wanted to seriously upgrade their living conditions with something more than a stagnant water dish that I'm changing every day or so...I want to filter their water, reducing the frequency of water changes. Space is the biggest issue here. I don't want to increase the size of the tank, rather I want to get as micro as possible with a filtered watering dish. Like the ones you can get for dogs and cats, but smaller.
Requirements:
- It needs to be as small as possible. No more than 6"-8" wide and 1"-2" deep.
- It needs to be EASY to change filter cartridges. Meaning, I switch out cartridges once a week. I won't pull out and disassemble an entire filter. These frogs are jumpers. This rules out all submersible filters.
- It needs to not be ugly. Semi-ugly is okay if I can disguise it with leaves and branches.
Nitrogen cycling won't be a concern, as I have a cycled aquarium and can bring over water and cycled filter media to this tank.
I don't really want to partition the whole tank to have a large swimming area, because these are tree frogs, and this is really all about drinking water and the occasional soak. I need maximum land.
So these are the options I was thinking about:
Option 1: Reptofilter (stand it up in the water dish)
On the upside, it's easy to switch out cartridges to keep the water clean. On the downside, it's ugly standing up in a water dish, and I would need a pretty deep dish (almost 2" depth of water) to allow for it. And there's lots of splashing. And no way to regulate water flow.
Option 2: External Canister Filter (hang on back or side or below the tank)
This one from TOM seems to be small and out of the way. So does the ZooMed Nano 10. I can adapt tubing to get to the dish, and maybe can even flip the intake strainer on its side with an extra elbow or two. I'd have to crimp or clamp the hose to reduce flow, which is not ideal, but this is the least unattractive option. I like that I could clean the filter without getting into the tank.
Option 3: Tiny Hang on Back filter (half buried)
And this is my craziest idea. What I have 2"-3" of substrate and this filter was buried 2"+ in it, with the intake and lip right into the water dish? I could cut the intake stem very short, and maybe use a piece of flexible tubing to flip the strainer on its side. It's a little bit ugly, but not as bad as the Reptofilter, and I can get the cartridges in and out very easily. And it has flow control.
Anyway, that's as far as my creative thinking could take me. What do you guys think? How do YOU provide fresh water (short of daily water changes) to your small tree and dart frogs?
Thank you!
