HELP: Huge Spike in Nitrite + Nitrate?

I've had my tank for about 5 months and was cycled a while back.

I haven't tested my water for a while because it seemed like all my fish were doing well until yesterday. I came home to find one of my new amano shrimps had flipped onto its side, so I knew something was up.

My water came out at
pH 6.4
Ammonia - 0
Nitrite - 5.0+
Nitrate - 80PPM +
18 gallon tank
Lots of plants
c02 tank with diffuser

I QUICKLY did a 50% water change.

I'm not sure what caused the spike but I'm afraid this could be due to several things.

1) overfeeding - a lot of times my tiny little raspboras aren't able to catch all the food and they hit the bottom
2) overstocked in a 18 gallon tank - I've got 15 tiny exlcamation raspboras, 3 yellow jacket endlers, 1 betta, 3 amano shrimp, and an ott. Is this too much? Majority of the fishes are tiny though
3) lack of water changing
4) there was a dying snail in there for a few days, but took it out about 4 days ago.

Would all 4 be causing this? or would some of the reasons above not cause this?

With the spike of nitrite and nitrate, i plan to be doing 25% water changes 2 times a day for the next couple days and then slowing it down to 1nce a day for the next couple days after that. Is this a sound plan?
