Neon Tetra behaviour (hiding)

[jonall]

I was wondering if anyone could shed any light on the behaviour of one of my Neon Tetras

I have 8 neons, I have had them for about 4 months. to start with all stayed together now a strange thing has happened i only ever see 7 of them together, the 8th is always resting in a small cave at the back of the tank blocked off by a plant which only the neons and a 3 month old mollie can get to

I have not yet been able to confirm that it is always the same neon, But it almost seems although it is resting during the day and the only reason i can think of is that it may rest at day and keep watch for the others at night while they rest.

These are true shoaling fish and do not take turns on watch. If the one is putting itself into a hole and staying there, it is feeling under the weather. A weak fish is a target for agression from even it's own kind, so it does what it needs to continue.

If it does not appear back with the group soon, you will likely notice it just goes away one night...

Hate this bring this old thread back up but I also am having that issue. I've had these tetras for 3 months now and all 10 of em were introduced together lightly.
Don't worry my tanks and parameters are all fine so no need to ask if ammonia or nh/nt are the issues.

1 of them is now hiding in a tree stump decor alone and haven't come up to eat when feeding time happens. I'm kinda worried and I've read that I should take him out before he spreads it to the others, but some also say that he is either injured or a lil weakend and just hiding and recovering.
I haven't found a legit answer to this issue yet but I will update to see if "how someone in this forums said it" waiting to die alone.

I also don't like bringing this post up, but I have to admit I have the same issue.
After researching, most said their fish died. Probably an illness or a severe injury it couldn't recover.
I'm going to guess he is dead now, right?
