Compatability Issues

[holidayinn]

I have a 5 foot tank with silver dollars, pleco and clown loaches

Everything was going well, then i put in a Jd and a convict, i plan at a later stage to put in an oscar.

When I put the fish in the jd was harassing the con, now its the other way round with the con harassing the Jd and everyone else too, over the last couple of days the situation has eased, although the con is def the ruler of the tank and chases mo/less anything/everything...the jd and con were fighting couple of days back but not seen any fighting since

i think there will come a time where the jd will be harassing the con again as the JD will get bigger, do u think this will be the case? at the moment hardly ever see the jd as its constantly hiding, will this behaviour change? will it be vice-versa when the Jd gets bigger?

I get the feeling that one of these fish must go..Which one would you keep and why?

Any opinions/advice is very greatly appreciated

the jack dempsey will probably kill anyone it doesn't like when it matures, including the oscar and convict. If it is a female dempsey it won't be as bad but they are territorial fish to start with so there is always a probability of future problems.
