First attempt at a fire salamander tank. Trying the bioactive approach with a temperate forest flair. Rimless 17 gallon and LED strip light with hydroton base layer, topped with ABG mix. Added springtails and a few isopods, which seem to be proliferating well. Might add a few more isopods shortly. Pillow moss for the ground cover in the front and terrestrial baby’s tears for the top part with a couple fern varieties and some ivy. The first three pics are about 4 months in, while the last was taken recently right after misting (hence the blurriness). I’ve added a polycarbonate lid that covers all but a 6”x6” cutout where the branches protrude. Temps are steady in the mid-to-high 60s F. I was hoping they would use the cave in the front for hiding but so far they seem to prefer to remain partially hidden under the “tree”, and will come out when nightcrawler pieces are dropped in.
