I fed blackworms for the first time last week. My treat this morning was the Betta Albimarginata 'Malinau' deciding they were cave spawners in the calvus caves.
I stack the caves on their sides for use in the panda loach project. I did not really expect them to be cave spawners but they seem to prefer it in my set up. Bottom cave spawning albimarginata transferring eggs, top of caves panda loach being panda loach. Has anyone noticed the albimarginata cave spawning in their set ups?
