I have a 4 inch black convict who for the last 3 weeks has hid behind the filter,so I decided to try and get him za mate,now I know my tank is kinda small 20 gal but since I put her in he has done nothing but harass her and chase her he has eaten for the 1st time in 3 weeks my question is will this stop or is she doomed?The guys at the lfs sayed this might happen for a little while but it has been going on all day,what do you guys think?
