Angelfish spawning in community tank
Hey everyone, Happy Friday!
I could use a little advice about a situation that has developed in my 75 g community tank. Two of my sub-adult angels (bodies about half-dollar size) have paired off, claimed 1/3 of the tank as "theirs", covered the green intake tube of the Eheim 2217 with eggs, and are religiously protecting them. They share this tank with 4 large adult rainbows (Boesmani and Turquoise), 3 slightly smaller unpaired angels, and a couple of SAEs. I don't exactly aspire to be an angelfish breeder, but to my surprise after 2 days the eggs have not turned the tell-tale opaque white as I have seen happen so many times in our discus tank. It's a little hard to tell what color the eggs are at this point since they are attached to a green plastic tube, but they are definitely not the white color that would indicate they are unfertilized or duds. So, here are my questions and concerns:
1. Is it possible for angels to successfully spawn and raise their young in an active community tank? I would move the pair to another tank but I can't exactly move the eggs that are covering the canister filter intake-tube. I also don't have a spare tank that would be big enough at the moment. All 6 of our tanks are at full-capacity and I really can't imagine where I would set up a 7th.
2. Are the rainbows and other fish at risk of injury or worse from the expecting couple? Right now it's just the typical chasing away behavior to anyone who dares to venture too close, but I've heard stories from other hobbyists who claim that spawning angels can and will kill other fish to protect their offspring. The rainbows generally steer clear of this pair anyway, but the smaller angels and the SAEs haven't seemed to grasp the importance of avoiding the "red-zone" and are constantly threatened and chased away by Big Mama or Big Daddy.
3. On the other hand, if these eggs do come to fruition and actually hatch into wigglers and then free-swimmers, would they likely be eaten by the rainbows and/or others? Would it be possible to net the tiny things out of there if I did have another tank available? Would I take the parents as well or leave them in the 75?
Sorry for the length of this post...I appreciate any and all advice!!
