Brisltenose Catfish and Silver Sharks

Hi All,

Before I begin, congratulations on creating such an amazing forum.

I have just been given 4ft fish tank, and I currently have in it some Neon Tetra's (10), Silver Sharks (5) and Harlequin Rasbora (10).

I was thinking about getting 3 or 4 Bristlenose Catfish for the tank to run around and "clean". I was hoping to get maybe a couple of female and a male, and maybe hoping that they would breed.

I have been doing my research on what conditions the Bristlenose like to breed in, but I haven’t been able to find if the Silver Shark's will go hunting for the young. The sharks are only young, and are no bigger the 6cm.

Has anyone had any issues with the Silver Shark?

Any advice would be greatly appreciated.

Cheers!
Kieran

    Never had a shark before but I imagine they are opportunistic scavengers and will take the odd fry if they can catch it.
    You really dont want 80 bristlenose fry every 3 weeks anyway. Just a couple surviving by hiding under driftwood until they get too big to eat is good. <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->

    Thanks Brengun, Would you suggest I get 2 BN's, maybe a male and a female, and let natual selection take its course? or should I just get 2 males and not have to worry about it all?

    Yeah, I had a silver shark once. When it got to about 13cms it started "hunting" when the lighs were out and killing other fish, so it got thrown in the neighbours pond. That was in a 4ft tank. If you've got 5 I'd get rid of at least 4 for the time being. They can get pretty big and once they start growing they get big fast.

    Hi LEG-IT...

    Thanks Isabelle, I just love the look of the sharks so I might keep them for a little longer and then maybe sell them... is there much intrest for bigger silver sharks?

    If you can afford them, get a few little peppermint bristlenoses. When they grow up they have pretty good sale value, especially the females.
    The sharks seem to like plenty of open swimming areas so if you add a bit of driftwood each end, the bns will have good cover and be able to stay out of the sharks swimpath.
    Bns eat wood and they like a bit of cucumber held down near them as well. They do eat a bit of algae off the glass but only the easy stuff and most of the time you will have to wipe it down yourself with a bit of old filter wool.

    In a group of 5 the sharks maybe well be quite happy and not get into mischief. The trouble usually seems to start when there is just one fish with nothing to do and none of its own kind to play with. Keep them well fed and happy.

    BTW Kieren, now you have two posts approved any further ones dont need moderator approval and will post straight up. <!-- s:dance1: --><img src="{SMILIES_PATH}/yahoo.gif" alt=":dance1:" title="dance1" /><!-- s:dance1: -->

    I have had Silver Sharks for years and the only problems with then is their speed, if startled they can knock themselves out by hitting the end of the tank, they are excellent jumpers I had a expert but one night he made a fatal mistake and jumped out through a 20mm gap in the top glass.

    Sorry to say a 4ft tank will be too small for them in a few years.

    Your tank requires a lot of planting for your fish to protect them from the tank lights, you will also require old soft DW for any BNs that is a natural food for then.

    Thanks for your advice Neptune. I was thinking about getting 2 lots of Amazon Swords and also a Java Fern, hoping that they will be able to grow and add more cover over time.

    With the light, what would the best type of Bulb be? I know there are alot and im not sure where to start looking...

    If that is a twin unit buy 1 daylight and 1 plant light tube

    If its a single get 1 plant tube.

    Finally go to Bunnings and get a simple timer and set it for 12 hrs of light.

    I went and saw Jodi at FishChick and got some plants for the tank, as well as two small common bristlenose. I also picked up a small bit of driftwood for them.

    Now to sit and watch these amazing fish... <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->
