| Behaviour | Details of the spawning are here: https://www.planetcatfish.com/forum/viewtopic.php?t=51942. Spawning not observed. Eggs found drifting around on the floor of the tank. | |||
| Eggs |  There were 60 amber eggs laid which were 1.5mm in diameter. | |||
| Time to hatch | 7 days Number: 0 Free swimming: 0 days | |||
| Segregation | Eggs were siphoned up with a turkey baster and moved to a 5 gallon tank to hatch; I also moved the spawning mops into the tank because I could see eggs on the mops. The next morning all eggs were gone. Unbeknownst to me, there was an adult T. gyrina hiding in the mop. I don't know if he ate the eggs but he may have. The next day I collected about a dozen eggs more in the parents' tank. All of the egg jellies appeared to be empty, as if the eggs had already hatched. Now I don't know if the original eggs I caught the day before even had babies inside, or were just empty jelly coats. | |||
