I also started dosing right away. Maybe not the best from everything I've heard so far.
I got 4 white clouds yesterday. I am going to add fish very slowly. I'm going to remove my stem plants. And cut back my melted crypts and maybe add some jungle Val in the place of the stem plants. And add some floating water lettuce.
Staurogyne Repens (tissue culture) Cryptocoryne Beckettii
Cryptocoryne Wendtii Green (tissue culture) Ludwigia Repens
Bacopa Caroliniana Red
Tiger Lotus Bulb
Dwarf Aquarium Lily Bulb
Jungle val grows really fast and the leaves will drape over the top of the tank shading what's below. It's a great look, but it will lower light levels for everything else, and you'll need to stay on top of the trimming. All those dire warnings aside, happy to gift you some val if you still want it.
Your Crypt balansae, once it recovers, should slowly grow into a great low maintenance background plant. At which point you can decide if you still want to keep the val.
I did a water change and stopped dosing completely. my crypts had completed melted. But my repens has new leaf growth at the very base of what melted. And still is holding it's shap and standing up straight. My bacopa also has new leaf grotlwth at the very tips. But my ludwigia lost like all of its lower leaves.
I'm thinking of pulling them out and cutting off the bottom and replanting them since I stopped dosing and see if they grow better.
I've decided I definitely want shrimp because with the fluval stratum substrate I noticed the fish food really falls into the cracks. I want the shrimp to keep everything well eaten.
I'm thinking of doing 3 small schools of different schooling fish. And the shrimp.
-6 white clouds
-6 ember tetras
-6 ? Of another small tetra
-12 Red cherry shrimp
I'm not sure need to research some shrimp safe tetra or rasboras that won't get to large.
White Cloud Mountain Minnows like much lower temps than most tropical fish--upper limit of about 72. There's not a lot of overlap in temp range between them and the embers. So just be sure to carefully research the optimal temperature ranges for your desired fish and shrimp. 70 might be a good temp for what you've chosen--in which case you might not even need a heater.
Tetras school better in bigger groups, so you might just want to go with 12 embers rather than trying to mix species. A nice sized group of embers schooling is a beautiful sight....
If your plants are melting slow down. Something is out of balance and your tank is not stable. My advice right now would be adding 6-7 ramshorn snails, changing 20% water twice a week, sucking up whatever melted plant matter you can in those water changes. Monitor ammonia/nitrites/nitrates and phosphates. Do water changes as needed to keep them inline.
Melting is common with new plants--especially crypts, and especially tissue cultured plants. Most commercially grown plants are grown emersed, so lose all their terrestrial leaves and grow new underwater leaves. Using some polyester floss in your filter should help trap some of the mess from the melt so you can easily remove it. In addition to snails, shrimp will also help clean up any melting leaves you might miss, as well as algae. Probably too soon to add RCS, but in the meantime ghost shrimp are cheap & easy.
Don't keep RCS myself, but everything I've read says you should start the RCS colony first, then add your fish so the shrimp have a chance to get established & breeding before their predators (for the babies anyway) get introduced. A nice patch of java moss somewhere will provide plenty of cover and a foraging ground
Good luck! Will be following to see what you end up getting, and how it works out....
