Thread: Cory Tank?

  1. #1

    Default Cory Tank?


    0 Not allowed!
    I am wanting to set up a cory tank and am wondering how many different species people think I would be okay with in my new 30g tank. It has a 31 x 14 inch footprint.

    I originally wanted a nice big school of Three-Lined (False Julii) Cories but my LFS has recently got in some Tail Smudge (falsely labeled as Tail Spot) Cories and I am torn between the 2, so I am wondering if I would have room for both species. Apart from the cories I will probably do a nice big school of Cardinal Tetras.

    If you want to put in Cardinals do have a thought about C.Sterbai or Duplicareus. They have the same (high) temp needs as cardinals.
    No Cory, No Glory !!

    I have had Sterbai's before and I didn't like them, and Adolfoi's Cories are out of the question as they are about $35 each here compared to smudgespots being about $15 and three-lines at $6. If the cardinals don't work I will change them as this tank is dedicated to the cories, not the tetras. I may go with Green neons or black phantom tetras instead. Or Green Flame tetras, which recently became available in my area and are STUNNING!

    Presumably the Tail Smudge are Corydoras similis. I suppose the "tail spot" might be Corydoras guapore. These are two of my favourites, and lovely corys. I currently have a group of four C. similis and would get more but they are very rarely available. I got the ones I have some 4-5 years ago. I have only once seen C. guapore locally, back in 1997.

    I wouldn't worry about the temperature for cardinals; while it is very true that they do well in warmer water (and are thus good with rams and discus), they are fine at more normal tropical temperatures. I maintain mine around 77-78F (24.5-25C). And these corys will be OK with that too.

    The false or green neon, Paracheirodon simulans, is a nice little fish, also very rare, but they can be rather delicate. I've had good luck and not so good luck with two groups of this species, but the bad luck was the origin (store).

    Be careful of the green flame, assuming this is Aphyocharax rathbuni which is sometimes commonly called the Green Fire. Stores often make these names up, so the scientific is essential to know. This beauty can be nasty, a real fin nipper, as indeed are all the species in this genus. It can vary, but if it were me I would not get these in this small a tank.

    To the question of numbers, the more the better. In a 31-inch length tank, you can go up to around 30 corys. They live in groups of hundreds naturally. Minimum five of a species is best, or more of course. And you can mix species with no issues. I have some 40 corys in my 115g tank, representing 12 or 13 species. Some I grabbed because it's all they had, others as you say were very expensive.

    Lots of chunks of wood, and sand substrate. Lots of plants, including floating. None of the corydoras appreciate overhead lighting that is bright. And the cardinals have a "light phobia" as Baensch calls it.

    Remember the cardinals are mid to lower level fish, so you may want to find an upper level fish to balance things. Corys, cardinals, and perhaps hatchetfish? The marble (Carnegiella strigata) would be nice here. Of the rocket pencilfish, Nannostomus eques.

    Byron.

  5. Default Cory Tank?

    I noticed it's no use trying to advise someone at the other side of the pond hahahahaha. 30 - 40 Corys is a 80 cm tank? I'd be shot overhere (Holland) if I'd advice that. I am keeping 10 in such a tank. Also keeping such an amount of different Coryspecies and shoals of 6- is thought about a little different ovethere. I am amazed about the prices btw, cause overhere 5 - 10 euro is normal. Hope you'll enjoy your Corys. They really are great! Cheers Aad

    Many aquarists when thinking of numbers of fish only seem to consider the bioload, but there are other factors. This is why the online calculators are frequently not all that reliable, they cannot consider all the factors.

    Though having said that, reading back through my previous post, I see I typed 30 when I think I meant 20. I often hit adjoining keys, and spell checkers will catch mis-spelt words but not words that are wrong if they still make sense, as here.

    Corys should be in groups no less than five of a species if possible; though I have some species with only 1, 2, 3 and 4 of the species. I try for 5+ but it isn't always possible for various reasons. Fortunately, they seem to settle in OK if there are more of them, whatever the species. I have four each of C. sterbai and C. duplicareus, and I frequently see one C. sterbai and one C. duplicareus swimming around and interacting. I guess they don't care.

    Byron.

    As Byron pointed out the Corys you like are probably, Corydoras similis, also called the "Violet Cory", I recently added a school of five to my 50g. They always stay together, sometimes joining the Bronze Cory's that have been in the tank for 3 years. I find them one of the most attractive of the species.

    I've heard that the Green fire's can be nippers but never experianced that in my tanks, keeping them alive was the problem I had with them, Strider199 gave me some good advice on them awile back, if I was to try them again. Great info on them here: http://www.google.com/url?sa=t&rct=j...55980276,d.cGE

    I realy enjoy my Green neon tetras and have found them to be hardier than most articles say they are. Their behavior IMO is more like Cardinals than neons. Crdinals of course would be my first choice.

    Two schools of five Corys would work in the tank your planing.

    Is the Cory in this video the one your talking about?

    what about some of these

    http://www.aquabid.com/cgi-bin/aucti...shc&1383706490

    I personally know both Lotsoffish (Pete) and Conrad from the local club, and both have high quality fish. Not sure what exactly you are looking for, but these guys aren't the most common type out there.

    Just a thought

    I agree with Bryon on the set up, my cories love driftwood, lots of plants, subwassertang (floating plant that sinks to the bottom but doesn't root) and sandy substrate. If you are looking to breed them make sure you don't have any snails (will eat the eggs) and if you add RCS they will help keep the eggs clean
