Well, you know you're overstocked, so I'm not sure what you expect people to say, tbh
It's also very poor stocking.
The angels need a tank that is at least three foot long by 18" tall. Unless you've been lucky enough to get a compatible pair, one will almost certainly bully or even kill the other. You'll need to get your four foot tank within the next month or two, or rehome them. Fish, like all living things, do most of their growing when their young, and they should be four or five inches long and six or eight tall by six or nine months old
The tetras and angels like soft water and the mollies, swordtails and guppies like it hard, and tend to do quite badly in soft water.
The mollies and swords get to around four inches, so are also far too large for this tank.
Cories should be kept in groups of at least six. I, personally, wouldn't put cories on the substrate; it's far too big and rough for their barbels.
There are no plecs that I would put into a 55l tank, not even bristlenoses. Maybe otocinclus, if the tank was well matured with live plants, or one of the dwarf corydoras species, but again they'd need to be in groups of at least six, and preferably eight or ten to do well.
I have one of these tanks, and I have nine glowlight danios and nine dwarf emerald rasboras, plus some rhino shrimp, and that's pushing it to it's limits, IMO.
Can I be cheeky and ask why you didn't come on here and ask for people's advise about your stocking?
