Did you add all these fish at the same time?
do you know about the nitrogen cycle?
Are you using water conditioner?
I'm asking these because it seems like you might be new to the hobby. I'm not trying to shame you only trying to help for you and the fish.
many of your fish need to be in larger groups. such as your 2 glow tail tetras (I have never kept these so i don't know for sure if they need to be in groups, but tetras usually need to be in groups of at least 6-8, also some types of tetras can be notorious fin nippers). Rasboras and mollies also need to be in larger groups with mollies needing a gender ratio of 3 females for every male.
Return the tiger barb. they are notorious fin nippers and even getting them in a bigger school might not cut down on this behavior.
The common pleco can get huge!!!! and they eat algae and stuff now but as they get bigger they get aggressive and have been known to attack fish and suck the slime coat off of them leading to injury and possible death.
I would check the compatibility of your two different gourami and your angelfish.
I don't know what a red minor is so I can't advise you on it.
2 blue ram cichlids: these can be territorial and aggressive. if they turn out to be of the same sex make sure you have two distinct areas for them on opposite sides of the tank. with rocks/driftwood and/or plenty of plants.(which you will need more of)
Angel fish can be aggressive too. Though I think maybe you could squeeze another into your tank but i think that depends on if you keep the gourami. I think if you want to keep your angelfish with other fish you will need a lot more plants. Plants will break up line of sight. for an angel fish when they chase they are often chasing things out of a territory. so out of sight out of mind.
I would suggest you do research yourself before buying anymore fish, and doing research to take back some of the ones you have already.
As for stocking, you need to look up how big the fish will get when it is an adult. there is a guideline that says one inch of fish per gallon. but it is always better to understock than overstock.
a good website to use to help you is AqAdvisor.com it will tell you which fish are compatible and if you are overstocking.
