Does anyone know why my Colorado Sunburst BTA always reaches like this and never make any bubbles. Had him for about 10 months now and got him when he was really small. And my clowns don’t dig him at all. Never even tried to host. Tried about almost everything. Even had them in a separate tank to force them to host but nothing. I don’t spot feed the Nem but he does get the odd mysis when I feed.
