I've got two texas cichlids the male is 6inch or so, and the female is 3inch. They were in a 6 foot but their tankmates started picking on them so i caught them out and put them into a 4 foot. Then i noticed that their vents were out. They changed colour and started tail slapping and started defending a large pot tube. They have stopping doing that now but what can i do to try and get them to spawn again. Thanks for any advice.
