Too many tetras...

to choose from!

I am planning the layout and stocking for my 30 gallon high and I know I'm doing a heavily planted tank. I know I want a decent sized school of cardinals 10+, but I have no idea what else to put in there! It's a very prominently placed tank in my living room, so I want something that is not necessarily flashy, but definitely pleasing to the eye.

Any suggestions?

I was thinking of eventually placing an angelfish in the tank, but I don't necessarily have my heart set on having one in *this* tank. It may end up being just tetras :)



EDIT: forgot to mention that my school of five bronchis splendens will be moving to this tank after it is established.

Angelfish when fully grown eat tetras.

Now what other tetras could you put in there, personally I'm partial to serpaes:

and rummy nose:

I love the look of the serpae tetras...

Will they be too nippy or aggressive with the cardinals? or will the plant cover take care of that issue? Do you think a school of 8 would be sufficient?

I know about the angel vs. tetra issue, that's why I'm probably nixing the idea. I don't have another tank to put an angel into once full grown, so it's better not to start off with it at all. (I'm already dealing with that "I'll get a bigger tank later" problem with the mbunas I have)

I think the rummy nose are cute, but not quite right for this tank. Any other light/white/silvery tetras? Maybe diamond or lemon tetras? I want one more small school (8ish) to round out the tank. I'm going to be over filtering (like usual) so I'm ok with being just a tad bit overstocked. (thinking 30-35 total fish)

I'm only passing on what I've read and heard. My tank is still settling in before I start to stock it.

The serpaes are more likely to nip long flowing fins and if they aren't in a decent sized school. Your cardinals should be fine.

The clear/light colored varieties never attracted me so I couldn't say.

+1 for the rasboras. I'm going to have a school of them in my tank eventually.

hmm... I like the rasboras, but I am going to have some kind of rasbora in my Asian river tank. What do you guys think of red eye tetras? The body shape (EDIT: fin shape, I mean, that black flag like dorsal) seems similar to the serpae, which I find attractive, but it has the flashy silver look that I want.

Cardinal Tetras, form what I've seen, spend their time near the mid-bottom levels of the tank. Since you like tetras like me, check out this link: and click on the tetras. IMO, I would get Lemon Tetras, or just do a small South American Biotope (I love this setup and wish I had room for it). 10 Cardinal Tetras with a handful of Hatchets for teh top (at least 6, maybe 8), and a specie of Corydoras for the bottom (again, at least 6). All of these fish have very little bioload.

Ooo... yes! Hatchets!!! that's the perfect silvery fish for the upper levels. The tank has a well fit lid too, so less risk of them making a break for it.

Thanks for the link. I like the idea of doing another biotope. I'm trying to set up an Asian river biotope in my 28 gallon (after I, y'know, move the cichlids and the catfish :)

I've noticed my red eye tetras tend to spend a lot of their time at the top of the tank. I really like the look of them, myself, and the big, flashy siver scales would contrast nicely withe the cardinals.

Black Neons and glowlights would also work with the cards. Kerri tetras, Red or Black minors (the reds look a bit like serpaes, but not so nippy).

Pencilfish would be nice and work the top of the tank.

+1 for getting a topdweller like hatchets. Halfbeaks are really cool as well.

Anableps are AWESOME if you can find them, but alas, impossible to find and too big for your tank. Just had to throw that out there though!
