I have a black water aquarium I wounder can I add dead fern as botanicals

Google says Phlebodium aureum. Is that correct?

Should i cut off the whole browning fronds or just the browning leaves? How do i save it and make it pretty again? 😭😭

She’s beautiful and she knows it

Please let me know what’s happening here.

Is this selaginella willdenowiii? The seller said he wasn't so sure, I'm trying to look at IG, but selaginella willdenowii so confusing, different lighting & temperature can change its color.

I just did a repot with 50/50 orchid bark and indoor potting soil with slow release fertilizer. I cut off the dead leaves and watered after the repot and am just leaving it. Photo of my fern

So I went to collect some spores from my Australian Tree Fern today, and I noticed many of the fronds had this mold on them!

I've had the plant for a few months and it has been very happy, pushing out new growth and looking great. I stopped, but for a while I was misting it with a spray bottle. I guess the place I had it did not have sufficient air movement, and here we are. :(

My question is, is there anything I can do? I cut off the fronds with the worst of it, but if I removed it all I'd have almost no plant left. What would you folks suggest in this situation? Thanks for taking the time to read this!

Back in September I bought a rather scraggly looking baby boston fern from an average hardware store. I initially just cared for it & made sure it got back to decent health before I considered replanting/fixing up soil. I have two questions;

1. why is it that when i leave it outside it gets upset & starts doing worse? I live in central Texas & from everything I've seen, theyre supposed to be happier in warmer, more humid climates, not inside the house where its 70 degrees regularly. I've tried putting it outside(in the shade of course) multiple times & each time it gets unhappy & starts having issues. Inside i keep it on my dresser, near a slightly pulled back curtain, where it's in indirect sunlight. I water it twice a week & mist it every other day, & when i shower i leave it in the bathroom while its still all humid. Is texas weather just not good for them? It does it's best inside & looks happy & healthy.
2. what soil would you recommend? I know it needs to have decent drainage, but how would i go about mixing that correctly?
