So I have other cichlids. Oscar and jack Dempsey in my other big tank. But I recently got my small tank. 20 gallon long cycled and decided to get convicts. I went to the store and got 2 small ones. Luckily for their size I could pick out a female and male fairly easily. But my question is will they automatically pair up ? Or should I add another female or 2 for options. I'm kinda hoping they will pair up naturally. And how long will it take for them to start breeding. Their small maby 1inch ish.
