They get listless, will hardly eat, get the curved spine, and then lay on the bottom unable to swim, except dart around in circles. M, MII and RidIch+ are useless.

If I lose them all, I only have 6 left, do I have to start my tank from scratch after tearing it down? Specifically, I won't be able to use the bio-wheel-gravel or any water to help the new tank cycle? Ugh, I don't want to start over. I could bleach dip the plants, right, and use them?

This is just awful, watching them die ne by one. It almost makes me want to quit fishkeeping as a hobby.
