Texas Cichlid Turned Completely BLACK!!

I also advise not to add anymore cichlids. Wait till a pair forms and rehome all the extras.
Peacock bass grow to gigantic sizes we are talking 20 inches plus. They are best suited for tanks 3ft by 8ft or larger.

Not my picture, thank google

If you are looking for more activity in the tank I suggest some dithers. In the wild cichlids live along side other fish like tetras, live barers etc. They use them as an alarm system of sorts. If they are out and about then things are OK but if they are hiding they know trouble is around and hide themselves. Look into swordtails or Molly's. Expect over time some may be lost to predation.
Keeping fish is the ultimate in long game hobbies. True results don't come in days or weeks, it's in years. Soon enough they will get big and you will be rewarded in know you raised them up. In time you will be rewarded with have a big beautiful male like this to watch.

And those two fish at the bottom of this photo what are those... honestly I am looking for a fish that gets big but not to big a fish that comes in all kinds of different varieties and colors and q fish that has different rarities so I can collect rare colors and such.... so I guess that's sounding like a African cichlid school tank huh? But I also want to keep some other species as well that get along but also have different rarities I guess

The fish in my pictures are what you fish will look like when they gain more size. They are Herichthys carpinitis. Alias Texas cichlids. Males.get to about 12 inch mark, females a bit smaller.

It's ok to be your first tank and make mistakes, I think all of us on here have, and some of us still do lol. But you're in the right place to learn. It does look like a 55 to me too, we can tell you if you measure it and tell us in inches, feet, centimeters, not just window sized. And if it's a 55 you can grow out a texas in it for awhile, but eventually it will need more space and more water. As Dano mentioned if you want a bustling tank full of fish then you need to go with african cichlids of some sort, or a community tank of peaceful fish, not predators, or cranky cichlids.
The problem with giant fish in a small tank isn't just about agression or fighting though, it also is about water quality. They poop a lot, they excrete hormones, leftover food, everything needs regularly flushed out and diluted by water changes, and having enough water to last between water changes.
