Bought a couple of "Calvus Spawning Caves" from Ken's fish. The image on the website looked like a wee triangular stone tent. These are made by hand from some sort of clay. What I got however, looked like the wee tent fell over after molding it and then got sat on before it got baked. It is pinched in the center. I know Calvuses/Compressiceps can squeeze a lot but even my little adults would never fit in this safely. I complained to Ken and he said I can send back for a refund ($4.95 each) but shipping is on me... so not much savings. Should I bring to the MAAH auction on Saturday? They would be fine for wee fry but I would fear putting them into a tank where a big fish could get his head stuck. If members think these are unsafe I will send back.
