Euphillia, I know you want nems, but the answers you are getting here are the exact same answers you have gotten in the other few threads where you have asked the same things.
I'll just get it out and say you can't/shouldn't get nem. Here is why (based on this post and your past threads)
1) The general concensus is that you need more light with Nems (a good T5 or MH setup)
2) You cant do an external MH or T5 because of parents and $
3) You cant do an internal T5/MH because of $, usable space (for individual reflecton on T5 which is what you'd need), heat
3a) a retrofit with additional PCs could MAYBE get you enough light, bit it is still $$, electrical installation work (a "qualified person" would need to do it)
3b) assuming you could do internal MH, or additional PC bulbs, you would have a lot more heat which means you need active cooling, which is even more $$
4) THere is no PC light you can swap in the hood that will significantly "upgrade" your tank.
Your track record shows that you will keep ignoring the sage advice of others and keep asking the same question or a variation of the question till you get the answer you are looking for. I hope you will break this track record.
