Serpaes Always Hiding, Won't Eat, One Died. Help!

About two weeks ago I bought 3 Serpae Tetras, then one week ago I bought 4 Longfin Serpaes (the pet store only had longfins). Ever since I bought them, they're all just always hiding in the back of the tank, sitting at the bottom. They don't swim around, they won't eat, I can't get them to come out unless I scare them out, and when I do that they dart around the tank scared to death, before going back and hiding. They don't even all stay together, they just spread out and sit at the bottom of the tank hiding. The tank is a 30gal freshwater planted tank, and it contains 5 nerite snails, 1 amano shrimp, and the Serpaes. Today I noticed one of the Serpaes was dead up against the filter intake tube, it looked like he'd been there for a day or so. I immediately removed him and tested the water. These are the test results: (tested just now)
pH: 7.2
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: 5.0 ppm
These are all safe and acceptable water levels, so why did the Serpae die? And more importantly, why are the other 6 Tetras always hiding and never eating? I'm worried the one that died died of starvation, because I can't get any of them to eat. I drop food in and it floats right past them, and they ignore it. I've tried lots of different kinds. If anyone has any advice on the subject, please help!! I'm very worried about my Serpaes.

 

You are right! Those water conditions are perfect! I think it may be starvation. Have they been Quarentined?
For how long?
What have you tried feeding?
What’s in the tank?
Ca you post a picture of the entire tank?
Ps. You tried everything you could.

Thanks for replying! That's what I thought, but they won't eat a thing! I don't know what's wrong with them. No, I don't have a quaretntine tank, plus they're the only fish in this one so I didn't think I would need to. When I first got them they would eat, and I fed them TetraMin Tropical Flakes, which they loved. Now they won't touch it, or anything else I try to feed them. I've tried flakes, pellets and bloodworms. Like I said, in the tank is 5 Nerite Snails and 1 Shrimp, all of which are healthy and eating normal. Sure, I can try to.

Does this link work?

 

The link works perfectly! Your tank is lovely and O don’t see a reason for them to only be in the corner. As for feeding, you may want to try baby brine shrimp. Whenever I have picky eaters, that’s my go-to food. If live food doesn’t work, you way want to take out some plants to make sure they are eating. They also may just be scared and warm up to the entire tank later.

Thank you! I will definitely try that, can you get it from petco? I've noticed they seem to be getting slightly less skittish, they're coming out a little more and don't all swim away when I walk up to the tank. still can't get them to eat though. I'll try the baby brine shrimp, if I can find some. Thanks so much for all the help and advice!

 

They don’t sell them at Petco or petsmart but amazon has the eggs. After that, you need a water bottle air pump and non iodized salt. Oh, and light.
