For a quarantine tank, and treating for parasites in mind, I would just get a 20g plastic bin and lay some reptile carpet at the bottom of it. Put some cleaned potted plants in there (ficus, umbrella, pothos) – either cover the top of the pots with small stones or better yet replace the soil with super soil since you have it. Also go outside and get some sticks – some small some large – make sure some sticks are small enough for them to comfortably grip. Clean the sticks in the bath tub before using them. Lastly, put a fluorescent fixture across the top with a 2.0 or a used 5.0 bulb. Obviously make sure no sticks or plants are high enough for them to get out. You want minimal soil – to better prevent parasites hanging out in the soil and getting reintroduced to the cham. This is just a larger scale version of what I use for neonate pygmies.
Mist them a couple times a day – really well in the morning and make sure the temps are around 75F. It should be pretty humid and wet in there after you mist but let it dry out and try to avoid humidity lower then 50. Your age/description was a bit confusing. If they around 2 months old then they will be pretty small – so maybe a 10g setup as I described.
That setup is easy to clean each week. I personally don’t treat for parasites – if you feed them well and take good care of them you may have it for a year to two with them just living with the parasites. Most WC’s I get die within a year – I sometime keep them for 1.5 or a bit longer but 2/3 die within a year for various reasons.
To effectively treat pygmies, you need fecals and maybe blood work done – several times. You may have to use several meds – some need may need to be given daily. If you are new to pygmies – this may be a bit difficult to do. Also keep in mind that if they are WC then they most likely have parasites – so it’s almost a given that the vet is going to find some. In the end it will be a long stressful process.
Where do you live? Is WC your only option? CB is readily available in the states.
