    Hi all , I read the previous article [thread] about Puntius’s Chalakkudinensis and Denisonii two i m o stunning aquarium fishes , I recently picked up five Chalakkudinensis from Pier Aquatics and though I know that when Niel [Pier Aquatics ] had a problem with aggresion among those Chala’s of his I was quite stunned really ,and tried to figure out why this senario may have occured , and all I can think is the tank they were held in was possibly too small , before anyone jumps to conclusions I hasten to add that Niels filter system is huge and more than adequate , so all I can assume is the space was too small , anyway the reason for me writing this is to rectify the situation concerning P.Chalakkudinensis, mine are absolute Pussycats , the tank they are in is 48 long 15 deep and 18 wide , they share the tank with five Puntius Mahecola ,two P,assimilis ,and three Botia Striata , the main difference besides a slight difference in colour is the mouth positions ,Chalakkudinensis have an inferior mouth position ,as opposed to the normal puntius mouth position of Denisonii

    Anyone who would like to try Chalakkudinensis should make sure their tank is long enough for them to have a good run [swim] /thumbs_up.gif” style=”vertical-align:middle” emoid=”:thumbsup:” border=”0″ alt=”thumbs_up.gif” />

    Nice to see a vote in favour!

    It’s interesting to note how being kept in the correct conditions (or not) can alter the behaviour of the fish.

    Andy, if you can get Mick to take some pics next time he’s over I’d really appreciate it. Decent shots of this species are basically unavailable and it’d be nice to add a species profile with the CORRECT fishes pictured (guess you know what I’m talking about here).

    From my brief observations and experiments I have found that trying to keep only one species of a cichlid in a 40 UK gallon tank has proved a disaster. Keeping a mixture of species of more or less the same size has resulted in a happy community. Of course, my fish are adolescents; as they approach adulthood, the story may change.

    You’d think that potential adult size would give people some idea about tank size. Keeping 6″ fish in a 24″ or 36″ long tank really won’t get them to show anything close to their true behaviour.

    I house my P. denisonii in a 60″ (l) x 18″ (w) x 12″ (h) tank and they look somewhat cramped in there. A tank with a footprint of 120″ x 48″ or so would probably show them off better. One day…

    It must be said that the lessons were soon learned and righted , by all parties !

    Retro have you disovered anything interesting with your Den’s I.e food preferences etc .

    How many are you keeping ?

    The only filters that I can obtain are internal power filters with course sponge inserts. I have cut the sponge in half and insert homemade gauze and cotton wool filters. This polishes the water to crystal clear. These filters cause quite a current in my meter long tanks ideal for fish who like fast flowing rivers like those mentioned. However the current can be controlled by increasing the thickness of the cotton wool filter and thereby reducing the filters liters per min output. By creating and controlling the current in a tank this gives the fish plenty of exercise and compensates for not being able to have a five foot long tank.
    Although all my fish come from a still Lake, the cichlids and certainly the characins enjoy coasting in the current. I have come to the conclusion that with plenty of exercise this is the reason that my cichlids are growing so rapidly.
    After all humans do the same thing. They go to a gym and run on a treadmill.

    Interesting tip there John ! so basically you are upping the flow , I notice the new Fluval internal filters have two outlets , a top and bottom basically :thumbsup:has anyone tried them ?

    Andy, I have 5 adults (4 males and a female) in there along with assorted danionins (D. dangila, D. assamensis, D. aequipinnatus, R. daniconius).

    The denisonii are not restless swimmers like the others, except when there is food in the offing. They are more Crossocheilus like than anything else when it comes to feeding, especially they way they run their lips over surfaces, looking for things to eat.

    My fish seem to prefer the lower levels of the tank and will only feed from the surface with great reluctance.

    John, you’re fish are probably growing well because you are feeding them well and maintaining good water quality. I don’t think fish bulk up in the same way people do

    Hi Retro, your Dens seem to feed in the same way as my Chala’s ? I know people have tried to reason why the different mouth shapes would be , i.e. different feeding methods etc , could it be they come from quite different types of enviroment i.e substraits , I’m guessing they must have a common ancestor ?

    Adaptation to different ecological niches would make sense and yeah Andy I doubt that colour pattern evolved independently in two different fishes. *scratches chin* We need pics!

    Thinking about it though they are less troublesome in the top tank that has an additional 2 feet of lenght.
    Well done for spotting that Andy … Now does anyone want to buy some of the more ugly ones

    Ha ha , Damn Niel you got me sussed /blink.gif” style=”vertical-align:middle” emoid=”:blink:” border=”0″ alt=”blink.gif” /> wouldn’t mind a few Dens but not sure if my eyes could take it /laugh.gif” style=”vertical-align:middle” emoid=”:lol:” border=”0″ alt=”laugh.gif” />

    Niel it would be great if you could get some pics done , Matty would appreciate that ! he has pics of Denisonii ! but none of good Chala’s , though I suppose a pic showing the two together would help people to understand the differences better !

    I don’t think their feeding habits are very different, Andy. I’ve mentioned as such elsewhere.

    Their habitats are fairly similar, deepish rivers with large boulders and strong currents. They’re also found sometimes in more open waters with sand or pebble substrates.
