First thing is if you like your aquascape, then it's perfect. Aquascaping is down to discretion. Shrimp also love mosses
Do you know what your water parameters are? Because if you are keeping shrimp then it is vital you always have a good idea of what they are.do you know what type of shrimp you want to keep? Caridina? As both have different needs. Also TDS, GH, KH and temperature are important.
I personally think a sponge filter is great!! As they create surface for biofilm to grow.
How are you planning on cycling your tank? As generally it will take some time to stabilize. Normally around 3 months if you want to do it properly.
Are your lights on a timer, as plants will grow at there best if you have a constant. Always same water, always same light. Slow adjustments are best!
I know it's alot but best thing to do while still setting up is making sure you as best you can. Find out all you can and then go from there. Anything else will just result in you lossing your shrimp and getting disheartened
Best of luck
This is my tank. I have airstones in, but I do does with ferts. Will be getting co2 hopefully next week
