I kept mine in the fridge in shallow water. You should change the water daily. They tend to foul the water really quickly and suffer as a consequence. If they smell bad you're not changing the water enough.
I've only ever kept mine for a few weeks so haven't worried about food. Apparently a slice of potato keeps them going but I can't vouch for it.
Jake I suspect you in fact have California Blackworms rather than tubifex. Google blackworms and you will find care and storage information. Truth be told, Mark's method works best. Keep them fridged and change the water daily removing any dead worms. To grow your own in any real useful quantity requires resources most folks do not want to spend time or money on.
Live Tubifex tubifex are rarely if ever available in the US these days. They are also a dangerous vector for parasites and disease in amphibians, farmed or otherwise. They thrive in low oxygen filthy effluent environments filter feeding off of bacteria and the like.
It works out well though, in North America we get black worms, in Europe they get T. tubifex.
Hi does anyone know if jungle fungus clear is safe to use for my axolotl? She has some either fungus or bacterial growth on her fillibrae and maybe body and I read that's good to use if you aren't sure if the problem is bacterial or fungal
Hi Delaney. Can you be more specific? There are lots of reasons for cloudy water, such as substrate getting kicked up, water hardness, etc. if you don’t have hard water and it doesn’t settle then I’d do a water change and see if that helps.
