@Lily Princiotta …is your chameleon eating now?
Is he still sitting on the bottom of the cage a lot?
Have you thought abou taking him to a good exotics vet before it’s too late?
Regarding using an incandescent light bulb for a basking bulb…I’ve used them for years. You still need to use a long linear tube UVB light …either a Reptisun 5.0 or an Acadian 6% so that the chameleon can produce the vitamin D3 it needs to be able to use the calcium.
You asked if that was too much calcium…this is going to require a long explanation. I’ll post it all in a few minutes.
First of all…I’m not a vet and can only tell you what I think from experience, etc. If we assume that the tongue issue is from an imbalance in nutrients….then correcting the balance should help the issue. However, we cant be sure that’s all that’s going on with him…a vet visit to an exotics vet would be the best option IMHO.
So…we dust the insects with a phos free calcium powder to make up for the usually poor ratio of calcium to phos found in many of the insects we use as feeders. We dust lightly so we don’t overdo it.
Now…the calcium can’t be absorbed into the chameleon’s system and make the bones strong and the muscles function properly without the right amount of vitamin D3.
The chameleon gets that vitamin D3 in two main ways…from the supplements we dust on the insects and from the D3 produced from its exposure to the UVB lights (Or direct sunlight). D3 from supplements is ready to go and can build up in the system leading to an overdose and to things like MBD. UVB exposure either from the bulbs we use or direct sunlight allow the chameleon to produce D3 and as long as the chameleon can move in and out of it, should not lead to an overdose….so we only give the supplement twice a month to ensure the chameleon has some D3 but it will have to produce the rest from the exposure to the UVB.
Now…vitamin A is another important vitamin and needs to be in balance with the D3. Vitamin A comes from 2 sources…prEformed and prOformed. PrEformed is ready to go and so it can build up in the system and lead to health issues. PrOformed needs to be converted into vitamin A by the body and cannot be overdosed. PrEformed sources are retinoids (and come from animal sources, etc) and prOformed sources are carotenoids…like beta carotene (and come from veggies and greens).
There’s more to it than this…but this should help for now.
You really need to get whatever his issues fixed quickly or you could very well lose him. Sorry to have to tell you this .
