planted tank and axolotl. what substrate?
Alright, I have been reading about sand substrates for a while and I am not sure what sort of substrate would be good for my predicament.
I have planted tank, of course, but I also keep axolotl in planted tank. Here is the thing, i need a very fine substrate, like sand or anything under 5mm. axolotl like to eat substrate, even if you handfeed, sometimes they just stick their face and suck anything. Axolotl can easily get pebbles stuck in him, this is not fun for Mr. Axolotl. Also, i keep Neocaridina shrimps, some with axoltol other in their own house.
What i need is a substrate good for growing plant, something axolotl will not choke on and one that will not leech certain material like too much copper that can harm my shrimps. Also, I do not want anything that will buffer my ph over 8.
Thankyou for help
