Melty mystery plant?

Hi everyone! I can't remember what these plants are, I got them a few months ago and while they've been growing pretty steadily, all the leaves have melted off of the majority of the stem. I was wondering if anybody knows what these are, and if thats normal for them, or if there is a way to make them look fuller.

Tank info:
Size: 20 G long
Parameters: 7.6 pH 0 ammonia 0 nitrite .5ish nitrate
Fertilizer : once a day with this fertilizer
Inhabitants: 1 female betta, a few bladder and ramshorn snails
substrate: sand
decor: dragon rock, driftwood, other plants and almond leaves

Bacopa, it's a marsh plant that likes its leaves above water. Once it has shed the lower leaves it won't grow them back. You can take cuttings and plant them or leave it as is.
