I just built an indoor pond that is 400 gallons?

Question

Is my setup okay cause I doubt my setup.
Setup of pond: Indefinite Shape, has a circle rock island with water trenches. Has a lot of plants below( Java Moss ). Depth is 1.5 meteres.
I also has fishes, this time, Im mixing tropical freshwater fishes with wild fishes.
10 Neon Tetras
4 Swordtails
8 Black Tetras
2 Deep Bodied Crucian Carp(Size:6"-1'00")
24 Chars(Size: 5"-2'04")
What other tropical freshwater fishes could I put cause Im just expert in wild fishes.
I have a very good filtration, air pump and heater.

Also I built a breeding mechanism for cherry salmons? I had it connected to the pond. It is a smaller pond that is 50 gal. and higher altitude( probably at knee level) and has rapids and waterfalls to get to it. No worries about the barriers and salting of the pond. I got 50 gal. from my pond and barricaded it, completely sealed, so the salt cant go to the other side of the tank. So the only size of my pond is 350 gal.

Is my breeding mechanism ok?

Answer 1

For small fish you could try Killifish. They come in colors that are rarely seen in freshwater fish.

For big ones..why not try a few Koi? They get large, they get along well with little fish and they come in every color of the rainbow.

Answer 2

How do you expect to keep the small tropicals (Neons, Swordtails, and Black Tetras) from being quickly eaten by the other fish in there? When you have a fish that is a foot long, there is nothing that is going to stop it from eating little one inch morsels... If you want to do wild fish, do wild fish, if you want to do tropicals, do tropicals, but there is no way you're gonna be able to keep them mixed long term...

EDIT: The breeding mechanism should be fine, but do you have somewhere to put the fry once they finally hatch? Do you have somewhere to let the fry grow out? The trouble with keeing native fish is their size, which you have to keep in mind, especially when you're attempting to breed them.

EDIT 2: All the tropical fish Chloe listed would either bully your fish, or get eaten by them... The Cichlids would be very uneasy with your water and the larger ones would probably go after your Carp. The small community fish would be an easy snack, and you already have Salmon... Gouramis need warm water, and I assume your pond for native fish (which need colder water) is unheated...

Answer 3

You could try small largemouth/smallmouth bass. you could try to have some african butterfly fish. they do well in big tanks. get more than one though. do you have a waterfall, if you do you can try small trout or salmon maybe. also loaches and plattys go good in tanks. the best thing though... try gormis(sp)sounds like(gromies). they go well with large tanks. i have watch out thought, they get quite big. also one last fish maybe. try chicklids or oscars. they like to be in a big deep place such as a 50+ gallon tank. they get quite big though.

Oh-oh.
