Peter McLeod Posted July 4, 2003 Report Share Posted July 4, 2003 I have a friend who is interested in breeding Discus and does not have access to a computer. They are blue cobolts about 100mm in diamiter. They follow each other around constantly.Would this be a sign of them pairing. Has anyone ever found a good way to sex these fish.

Chris.L Posted July 8, 2003 Report Share Posted July 8, 2003 You can't sex discus until they spawn. Quote Link to comment Share on other sites More sharing options...
dave Posted July 10, 2003 Report Share Posted July 10, 2003 Hi Peter I have bred Discus and sexing them is very hard . What i sugest is when you have a school of discus and you do noticed that two seperate out , becoming agresive to others in the tank you can almost say you have a pair . Once you have identified this condtion them up , Give them there own tank with a piece of slate , a upright pipe and i have seen discus cones and see what happens . You will only know then who is what . I have offen got it wrong . Hope this helps abit and if you want any other advice on breeding Discus let me know . I am not an expert but i will try and help Quote Link to comment Share on other sites More sharing options...
peety Posted August 5, 2003 Report Share Posted August 5, 2003 I had some for a while..... If you go to simplydiscus.com you will get the full low down but from memory.... you follow the line of the fins through to the tail. If the line misses the tail fin then its a girl, if it cuts through the tail its a boy (ie larger tail in relation to overall body). Amazingly this worked for me, and i could pair my fish Sometimes same pair get together if there are no other sex fish so you will never know. (I had two females pair up, lay eggs , and brood over them....) I had a pair with female bigger than male.... (normally other way round) Deliberately pairing doesn't always work either (tried it) because one sometimes isn't ready for settling down.... Discus are really hard to breed... but well worth the effort... good luck Quote Link to comment Share on other sites More sharing options...
