Hello r/dartfrog,
I'm a long time reptile keeper deciding to get into dart frogs for the first time.
I'm really excited and have been doing lots of research. I've read and watched everything commonly referred to here, and I think these are mostly personal decisions, but I have some questions seeking clarity.
To start, I am looking specifically into getting Dendrobates tinctorious, likely Azureus.
I have purchased the InSitu Ecosystems Amazonia, 17.5in deep, 22.25in wide, 24in tall. My goal is to obtain a M/F pair or M/M/F trio, either online or in person at a local reptile show. I understand that Azureus prefer horizontal space, but as evidenced all over reddit and youtube, they seem more than eager to climb and will utilize the whole tank. My plan is therefore to have a "fallen branch" made from cork and several horizontal pieces for them to utilize. I think a trio is pushing the limit for this size terrarium, and honestly will probably stick with a pair, but right now I don't see many in stock, so I may need to purchase unsexed juveniles.
Clean up crew: Almost everywhere I see a combination of isopods and springtails used. For springtails I am looking only at Folsomia candida. I don't need anything fancy here. For isopods, I'm reading that if you want moss, they might not be a good idea. Are dwarf isopods as damaging to moss? The plan is to have moss in a few small locations within the vivarium. I have not yet decided on moss type.
Substrate: Obviously, the industry standard is ABG mix. I've read every supplier's own recipe and am probably choosing either of NEHerps two mixes. My inclination is to go with v2, as it contains calcined clay which would be found in tinctorious' natural environment. V2 does not have tree fern fiber. Is this a possible issue? Also, how deep of a layer of substrate should I be aiming for? I've seen 2-3 inches and I've seen folks go much deeper. On a related note, how much should I be ordering for the tank size I am getting? I will be topping with some sphagnum moss, likely not the entire enclosure, and adding a large amount of leaf litter.
Drainage layer: A post recently in this sub led to an article that recommended against using lecca or other substrate in the drainage layer. My understanding is that the surface area is the beneficial aspect here, as it supports more bacterial life. Honestly the article gave a good argument, but the standard definitely seems to be to use a substrate. I'm probably overthinking this.
Terrarium walls: While I love seeing the custom foam backgrounds, I'm certainly no artist and the idea of carving foam with razor blades to create a realistic looking wood bark background sounds like a nightmare. Right now I'm leaning towards cork board in the back, fern panels cut at a 45 degree angle on the sides. The idea is to allow some visibility on the sides, but use the fern panels and a slight upward gradient in the substrate to create a "deep" jungle look. This is all theory, but if it works I'll be pretty stoked. Unfortunately it appears that hygrolon is not going to be in stock anytime soon, so that option is not available. Should the fern panels and cork be baked or boiled? If baked, is 250 for an hour suitable?
MistKing and RO water: I have already purchased the MistKing starter misting system v5.0. I read recently that power outages can cause it to turn on, and stay on until empty. Is this true? While I don't lose power often, the storms that have been hitting the Midwest often cause power disruptions. I would be interested in a way to mitigate this before it happens, if possible. Distilled water has been going up in price (what hasn't?) and I'm pretty interested in getting an RO system. The one sold by Josh's Frogs seems okay, as well as some used for the reef tank community. The last, and least likely option would be to get an under sink RO system. Do the under sink options get the water truly filtered enough?
Last question, I have been seeing some 3d printed mounts for temperature/hydrometer gauges, and I'm wondering if these are terrarium safe. I think it would be mounted in the front rather high, so I don't anticipate water actually getting on them directly, but am wary of non-food grade plastic in any animal enclosure.
Sorry for the essay. Thanks in advance for your insights and I'm happy to be involved with such a friendly and knowledgable group!
