hi there! so, i'm trying to incorporate live plants into my bettas tank but i don't think i'm doing something right. i only have water wisteria and anacharis in the tank, but i feel like both are dying faster than they are growing. what i want to know is:
1. am i doing something wrong? the stems of my wisteria are turning brown (except for maybe one or two of them) and i'm having to trim off the dead portions at every water change (once a week). the leaves are also turning brown, starting from the tip of the leaf as opposed to the base/stem. as for the anacharis, i just feel like it's not growing at all. the ends of its leaves are kind of translucent & brown as well.
2. would a (better) fertilizer help? i have Seachem Flourish Comprehensive, but honestly? i don't feel like it's really doing anything. also, it might be beneficial to note that i have a mystery snail in this tank so if it has a substantial amount of copper, i can't use it.
i have most of the wisteria in the substrate (gravel) with four smaller pieces floating. the anacharis is in the substrate. i also have a marimo moss ball, but aside from it splitting in two, i'm not really worried about it.
i'm not sure if this is relevant, but my tank is currently at 80 degrees. my room is always warmer than the rest of the apartment, so it kind of stays there no matter what i put the heater on. and last time i checked, the ph was at 7.4.
thanks in advance for any advice!
