I have a mated pair of Jack Dempseys that are 4 1/2 inches.They have bred 3 times in the last 4 months.How long do they breed for?A few months,a couple of years?And if I were to put them in a tank with other Dempseys will they try to breed there together or find other mates?Are they a mated pair for life as long as they are together in the same tank?Also if they are separated,will they try to breed with other Dempseys?Sorry for all the questions,just wondered.
