sometimes a few smaller groups captivate n look more natural n stunning then 1 spiecies jsut a thought

Hey Tiger, what type of A. Calvus is it, Black, yellow, white etc.

P.s I think Calvus are great looking fish, I'm planning to keep a few in my 125g tank which is currently being setup.
Hopefully I can breed them.

*UPDATE* the calvus has been moved to the 55g. with my p. ponelli and p. senegalus. they are doing great. no fights, skirmishes, nips, NOTHIN. the ponelli is afraid of the senegalus, and vice versa, so they dont mess with each other at all. and the ponelli doesnt mess with the calvus at all, and just recently i caught the calvus giving a bit of chase to the ponelli, scaring it out from under the calvus's fav. plant. SO, now im back to square one, an empty 20g.(standard) its actually kind of a weird tank. its not as quite as tall as a 20H and not quite as long as a 20L, but its dimesions calculate to a 20g.

You might be able to try Buenos Aires Tetras. I think they are more tolerant of high PH's and water hardnesses.
I kept mine for some time at a ph of 7.8 with water hardness of 220ppm, then we moved where the ph was 7.6 and the hardness was off the chart at over 360ppm.
These tetras thrive anywhere. Bigger too, so less likely to get eaten, and in my opinion, one of the most attractive of the larger tetras, so pretty with the silver red and black. I now have mine in a ph of 6.6 with hardness of 150ppm or so, and they have gotten more colorful, but they were more or less thriving before in much different water conditions as well.
Perhaps an option for you. They grow super quick too and often are very cheap.

I would have thought mixing Altolamprologus calvus, which is a Tanganyikan Rift Lake Cichlid, with Cardinals from blackwater biotopes was a recipe for disaster even if the Cichlid didn't eat the Cardinals ...

Nah, congos go for the acidic backwater stuff, too. You may as well just get some julis and shellies and call it a day. :[

very aware of that fact, which has been most of my problem. there arent any tetras that thrive in the ph of most african waters. possibly the congo tetra but i havent really checked it out yet. not a big fan of them anyway. figures, the one tetra that may be good in the tank, is the very one i dont want.

I'm sure you're aware, but remember Calvus prefer harder high ph water, while tetras prefer softer lower ph to thrive.

I'd go for something a little larger than tetras, or at least get one of the largest tetras. A. calvus are opportunistic hunters, and will eat any fish that is small enough. They reach six inches in size, so I'd recommend three inch barbs or tetras. Gold barbs should be okay, congo tetras, Buenos Aires tetras, etc. I agree in that you shouldn't buy the cichlid an expensive snack!

yea they are, but with a school of big enough fish it really shouldnt be a problem. n like i said this guy is very very small. probably to small to put down a juvi. neon, and an adult is out of the question. but yea whatever i get ill have to be careful n not just provide an expensive snack for him

Calvus are piscivores, though, aren't they? Not exactly something I'd want to keep a school of tetras with...

I'm not your neighbor, you Bakersfield trash.

im kinda embarassed to say it but the fish i finally choose for the tank is an altolamprologus calvus. im still thinking of adding a school of somethin or nother to the tank cause the calvus is extremely small. but ill wait to see how he does in the tank by himself. thanx for ALL the great suggestions and ideas. ill definitely keep them in mind for when i set up my 20g.long.

gold tetras n cardinals n harliquin even tho there not tetras look great in an all black tank with just javca ferns


neons glolites gold jellybean cardinals black pristellas diamonds there all amazing fish

i have an open 20g. n i was trying to decide on a good school of tetras for it. of course cardinals n neons came to mind first. but maybe pristella or possibly diamond tetras? i want a decent sized school, no less than 7. what do yall think? any other candidates off the tops o' ur head?

yeah sirbooks is right insyead of an angel mabe try a ram

so this is my new improved suggestion

6cories
7 cardinals
7 lemons
1 ram

I have a 20 gal w/black background, black gravel and an actinic bulb. The fish I've got in there are 5 neons, 6 glo lites, 6 black neons, a pearl apple snail and 6 albino cories...I LOVE it...it is so great! My hubby didn't like the sound of it but now that it's up and running he loves it! Anyway, just my opinion....

Or if you want something a bit different, you could try sailfin tetras (Crenuchus spilurus). They are awesome... Beautiful colors when mature, and what's really strange is that they act very similar to cichlids! Think of them as hybrids between normal tetras and rams.

When they "hover", they wave their dorsal and and anal fins just like cichlids do. They are not schoolers, and are actually somewat territorial to each other. If you keep the tank planted and have driftwood and everything, you could probably keep about five in there (they get about 2.5-3" long). Also, they do best when they are fed small amounts throughout the day, as opposed a single large meal.

Tetra only tank.... hmm---How about:
6 marbled hatchets,
2-3 splash tets,
6 black neons/ cardinals.
Looks like a winner to me.

or

3-4 headstanders
7 cardinals

or

3 beckford pencilfish
6 cardinals
6 rummies

Well, since your tank has a dark substrate, and is dark overall, I'd suggest cardinal tetras. They are quite small, and are very beautiful with a dark substrate. If you can find them, cardinal tetras would probably be the best choice. They look absolutely fantastic in a school.
