I got a little fish surprise (I think)

So 5 months ago I wemt to these islands in spain and to remeber it I grabbed some ocean water, sand and shells. I put it in my plastic bottle and then transferred it to a container. And I just got back to my country like 3 days ago. And I took it out from my suitcase and noticed something was moving. Is it a fish? It's swimming non-stop so I cant get a good pic. The lid was on for past 5 months and I didn't put any fish food in the container (cuz I didn't know there was a fish there) so what is it? Can somebody help? Do I feed it or just leave it alone? Pls help and thanks 😊

Smiley face :)

Didn't notice the spots until I got this home. Agree that it looks like a smiley face? Or a scary face : | ?

Is my Wrestling Half-beak acting strange?

I just wanted to know if this is normal behaviour for a Wrestling Half-beak?

I have never owned one before but I bought a female one around 2 months ago and she seems healthy, but from doing research online, apparently they like having slow flowing water but she seems to like the opposite.

Every time I go to check my fish throughout the day she will be swimming against the fast/medium flow coming out of my filter, she has many places at the top of the tank where there is little/slow flow and yet she chooses the fast flow.

I have also noticed a small amount of times, her swimming at the bottom of the tank probably scavenging food which I think is normal for any fish but she also sometimes hides among the plants at the bottom

I have 17 neons tetras, black and normal in there with her, could they be bullying her and i just haven’t seen it?

What's the smallest non-corey catfish in the aquarium hobby?

I like coreys, but I like catfish in general to. But I also do not have the budget for big fishy and big tanks or ponds, so small fishy is the only fish I can keep.

Bichir

With taxes coming in we are trying to prepare a tank for bichirs. My husband has always loved them and we’ve been wanting to add an “aggressive” tank for some time now. I’m trying to figure out what size tank we are going to need and what kind of tank mates we can have for them. We were thinking 75 gallon but from what I’ve been seeing that might be too small. Also can plecos live with them?

What type of fish is this?

A friend of mine sent me this picture, we’re not sure what type of fish this is? Was found near brackish water in Delaware for context.
