MTS are great assest,but they multiply quickly too.
and can b eaten by snail eating fishes too.
every time I introduce them,they end up as my betta's meal.
And they does the job of moving substrate quite good.
It decided to throw up a runner and I couldn't bring myself to pinch it, so I thought I'd document the bloom.
The runner is about 8 foot long now. I think it's that long because it kept looking for a way to get above water (there's not much room between the waterline and the glass top in that tank).
The bud was a couple of inches long.
The flower is now almost 5 inches tall.
Sunday when I was doing water changes, it started poking its head above water.
