Thanks everyone! I didn't do anything special to get either pair to breed. I bought four young angelfish about six months ago, and four Bolivians about a month ago from the same LFS. The angels were bred by another customer, and the owner ordered the Bolivians in.
Here's the specifics of my tank:
- 55 gallon South American biotope with Cardinals, cories, head and tail light tetras, angels, Bolivians, and a bristlenose pleco
- PH: 7.6, drops to 6.6 with CO2
- Temp 82
- Nitrates are dosed to 20 ppm with Estimative Index dosing
- Tap water has between 1-2 dKh, and 7.2 PH after gassing off, so I add crushed coral to the filter to buffer it. The dKh of the tank water is 5 right before a water change.
- I feed Hikari frozen bloodworms and Tetra tropical flakes, plus shrimp pellets, zuchinni, and algae wafers for the cories/ bristlenose
- The lighting is on for 8 hours a day, and it set to a timer. CO2 comes on with the lights, an air pump/stone comes on after the lights go out.
I'm trying to figure out how I'm going to save these two batches. I've got a feeling that bristlenose is going to be a happy camper if I can't figure something else out. Anybody ever try hatching these without the parents in one of those hang-in-tank specimine keepers? I can probably go get another ten gallon tank/heater/foam filter tomorrow. I've got a ten gallon hospital/quarantine tank, but it's got another bristlenose in quarantine right now. He'll go into another 55 gallon I'm doing a fishless cycle on. I know that the parents will take care of the eggs as best they can, but that bristlenose is about 6 inches. Something tells me he'd win.
Any help would be greatly appreciated!
