| Behaviour | Did a cold water change to induce spawning the corydoras atropersonatus. There has been, and will be, some thunderstorm in the area. I changed the fish from another tank 1 day ago. 1 of the females was very large (almost looked bloathed). The male swam through the tank like a mad man in search of the female. Once he found her, he would move in front of her head to get her to assume the "T" position. I witnessed this a few times after which the male swam of and the female stayed at the place she was hanging. She depostited her eggs on different plants. On the Echinodorus, the Crypto and the Hydrocleys Nymphoides. She deposited 1 egg at a time. After each egg, she would swim of to find a new spot. This new spot would first be cleaned by the female. I happened to catch it on film... https://youtu.be/N7dFiJVxqT4 |
| Eggs |  There were 19 white eggs laid which were 1.0mm in diameter. |
| Time to hatch | 3 days Number: 5 Free swimming: 2 days |
| Segregation | The eggs were taken out of the tank in a seperate canister with some elder cones (anit fungus) and an airstone. 6 eggs were laid on the Crypto, which was taken out and put in the seperate canister aswell. On thursday the 1st, the 1st free swimming baby was spotted and later that day, 5 were observed. The eggs that were taken out by hand all turned white from fungus. 5 of the 6 eggs on the Crypto were still clear and turned out to be the eggs that produced the baby's. The baby's were swimming with a Yolksag and already clinging on to the sides and the leaves of the crypto. After 2 days, a little bit of Artemio Fluid by JBL was introduced as a foodsource. The baby's seemed to respond by swimming around in the same way Otocinclus and the full grown Hisonotus are searching for food. |
| Fry sizes | 7 days: 5mm 14 days: 7mm 21 days: 15mm |
| 7 days |  |
| 14 days |  |
| 21 days |  |
| Juvenile sizes | 1 month: 0mm 3 months: 25mm 6 months: 0mm |
| 3 months |  |
| Fry and juvenile feeding | Twice a day, all water was changed and with the new water (from a matured tank) i also added Artemio Fluid (from JBL). Since the fry and juveniles had dark bellies, i assume they have been eating it very well. There was also a piece of leave from a echinodorus bleheri introduced with some algea growth on it. This is their favorite spot to hang out. |
