I agree, this set up isn't really suitable for fire bellied toads and I only see one light, when anoles need both a heat/spotlight and UVB. For the fire bellies you need a 10-gallon long as a minimum but a 10-gallon high doesn't offer the same amount of floor space as this. I would even go larger, 6 of mine are kept in a custom 70 x 40 x 40cm tank, which is an ideal size. They also need more water, around 50-70% and land from driftwood, stacked rocks or a glass divider with substrate. Use water plants such as duckweed, Amazon frogbit, elodea, etc. They also bask often so I use a 25W spotlight over the land and 5% or higher UVB light is also beneficial. After basking if they need to cool down they will go in the water, as Eric pointed out. Temps should be 70-80F with the warmest at the basking spot and anoles need it warmer. If you want to mix both fire bellies and anoles then a very large tank is needed. It can work, if animals are tested and treated for any disease but there might still be a risk of disease from natural pathogens that either might not be immune to.
