I want to start by saying this is an advanced question. I have been breeding angels for over 2 years and raised many successful spawns from numerous different pairs for multiple generations. So I know all the basics and then some...... The culling topic is something I have always struggled with though. But the larger my spawns have gotten....I can't keep trying to "save them all". And bringing them to the LFS with cosmetic flaws is embarrassing and it is considered a disservice to the species in general. I have done a lot of research on the topic. And I read on the angelfish society website, which "traits" are genetic and constitute culling. They list four things: Gill plate deformities, deformed or missing ventrals, Anal fins bent rearward, and belly sliders. The issue I am dealing with is none of those 4 things. I have about 150 blue pearlscale angel babies right now. All of which are at least dime sized or larger. There are just a few with severely bent ventrals or missing ventrals, I don't see any gill plate issues, or belly sliders. So that is all good!!! BUT about 10-20% of them are having their dorsal fins get droopy bends at the tips of them. Some of them have the anal fin bent as well. I guess that fits into the "bent anal fin" category. But the angelfish society didn't mention the dorsal fins bending. And that is where my main issue lies. Many of them have perfectly normal anal fins, but the dorsal has the bend. Whats frustrating is that everything I have read suggests this would only be caused by overcrowding and poor water quality. (Free Willy anyone? lol) Neither of which am I guilty of though!! My fry tanks get water changes daily, or every other day at the least. The tanks are appropriately stocked and the water quality is perfect. SOOOOOOO...my question is, could this be a genetic thing and there is nothing I can do about it? I had the same thing happen with previous batches of babies too. Different parents. But again, I take immaculate care of my fry. So I just can't believe that I am causing it somehow. And it is usually just a small % of them that get the bent fins. The majority develop wonderfully. I would think it would affect the MAJORITY of them if it were something I was doing wrong. Rather than the minority.... With that being said, if it is genetic, I assume then, that I need to cull that 15-ish% that are developing those bent fins? Its so hard to consider because they are so beautiful and healthy despite the imperfect fins. I have larger cichlids that I can feed the culled fry to. But at dime size, that will be hard to watch!!! And if I have to cull like 20 or more....I will just be very sad about that. I've got approx. 150, like I said, so the majority are looking excellent. But I refuse to bring fish with bent fins to the LFS. I did it a couple times, just a few of them, and it was genuinely embarrassing! lol Everone's first assumption would be that I am caring for them poorly, and that just isn't the case! So with all of that being said....could the bent dorsal fins on 15% of my fry be genetic and require being culled? Or is there something I need to be doing differently? I have raised many stunning angels into adulthood....and brought tons of gorgeous fry to the LFS...but I am afraid I need to cull these bent dorsals and that really stinks. @chromedome52 @AlyeskaGirl I don't know who to "mention" so if anyone knows any other members who may have some insight, please mention them for me! Thanks!!! wow.....that got really long. Sorry.
