I am sure that some of you have kept/keep a red tail shark. I have read everywhere and read on other forums how ill-tempered they are. mine is far from a little terror and just spends all day nibbling algae off the caves.

How big is it? They are usually peaceful until they reach a certain size then - wham! They attack everything. I wonder if males are more aggressive than females? This might make a difference to their behaviour

currently its ~8cm. They go mad huh? I wonder how the other fish will react, although they all are pretty tough.

Hey they don't all go mad - probably just the male ones :lol:

The female ones just get extremely bitchy for a few days every month.

he/she got done over by the spawning chromides a week ago. My shark doesnt seem to be as much of a 'people fish' as my cichlids and tigerfish.

At 8cm you have been given a great chance to make a name for yourself if you could find a mate of similar size.

Don't know if anyone has bred these or not, but they seem to be always in demand. JMO :)

Red tailed sharks have been bred before, I saw in an old TFH the FNZAS president currently has. They were bred using hormones, carp species i think, tricky but probably worth a go.

Little bit of fishy viagra, mood music on some waterproof speakers in the tank, a few candles outside the tank....Hehehe.

Sounds (excuse the pun) good, but will it work... Must try that sometime

Many years ago I had a tank with quite a few Red Tail Black Sharks in. Pretty big fellas they were, and I always had visions of breeding them.

One interesting fact I noticed was that if ever I was cleaning out and stirred the muck up, the RTS's would start to shimmer and shake like a spawning act. It certainly wasn't stress, as they would occasionally race around the tank, return to their favorite spot, then re-enact the, "what I can only describe as" their courtship dance.

Similar things used to happen with my big Plecostomus's, and occasionally my Clown Loaches.

Could it be that they spawn during the rainy season when the rivers begin to flood and stir up all the sediment?

Who knows, but the person that could spawn them naturally is obviously onto a winner.
