Honduran Red Points

[MattCurnock87]

Hi everyone,
I have just joined the forum to gain a bit of knowledge around my cichlids. I've had my 2 Honduran red points for some time now and I know I've got 1 male and presumed I had a female too. The smaller one which I thought was a female due to its smaller size and different shape has now grown considerably in the last month or so. they have previously got on fine however since this growth spurt they have now started to fight in various ways. I'm just trying to get peoples recommendations as to how to proceed as id rather not have any injured fish.
Thanks in advance, Matt
