I used to use several bamboo plants in my tanks, bought from Walmart because they were so cheap and some of them lasted. They went from store shelf to the tanks, and for years everything was fine, then I bought a new batch of bamboo plants and to my horror a week later I had a tank full of non indigenous spiders the size of specs of sand. I used a powerful magnifying tool to confirm they were 8 legged, but I could not identify the spiders. I tried contacting the company (from florida) that manufactured them but got no reply. I ended up gutting the tanks, putting the jungle vines, fake plants dishes and hides in very hot water, washed the tanks inside and out, tried soaking the bamboo in vinegar water (plants died, oh well) and hoped for the best. Now I quarantine my bamboo plants, transplant them into something different and things have been fine now for 2 years
