My goldfish randomly spawned

Hey guys, don't know if you remember me or not. Haven't been on in forever due to college. I have a female orange fantail, a male black moor, a male lil head, and a juvie (thinking male as well) fantail into my 55g. Here's how everything started ...

My mother-in-law's rainbow shark was attacking my goldfish. My MIL's 40GB got poisoned from our vindictive guests, so we had to completely tear down the tank. The few fish that were in there for moved to the 55g. Well, I put my goldfish into a 20gL to keep them from harms way. It took me a few days to feel good enough (I'm severely sick) to try to catch the shark to rehome him to a friend. After I caught him, I put the goldfish back into the 55g. I got sicker that night, so I left the 20gL alone. Well, now I have roughly 30-50 free swimming fry in my tank!

Now, I'm wondering who might be the main father, because although these guys are already free swimming, I see no dorsals. Do they grow later on or do I have a bunch of lil head crosses on my hands? I'm really looking forward to raising these guys. I've had them for about 3 days and they've already doubled in size and they're getting fat from the egg yolks I'm feeding them. There are no bait shops or pet stores around here, so egg yolk is all I can feed them.

So, my question is if they grow their dorsals later, when are they visible? Also, when do their tails split? All of mine still have a single tail.

So, I'm wondering how long I can keep these guys in here and how quickly they'll grow. I have no other tanks available for smaller sizes, but I have a 50g pond I can move indoors. After that I have a 100g pond outside.

Soooo ... yeah. Thank you guys for looking! I can try and take come pictures,but not even my FujiFilm on super macro can get them. They're so adorable!!!

For baby food that isn't as messy as egg yolk, go to a health food store and get some spirulina powder.  (I'm not recommending the particular product in the link.  I just wanted to show an example.)  Give the babies a little pinch several times a day.  When those little mouths are bigger, you can grind up some quality pellets to make baby-sized pellets.  

 

Newly-hatched goldfish do not have fins yet.  If you had both single-tail and twin-tail fry, you would be able to tell them apart.  The singletail baby fry just taper to a point at the end of the body, and the twin tails have a little knob at the end.  

 

I like to grow babies in a duckweed tub.  That  50 gallon pond would make a good tub for them once you feel they have outgrown the 20L.

Thanks! While I fed them this morning, I noticed that they are doubletails. Thank you for the insight on the fins. I can try the powder. I have high quality goldfish pellets to crush up later on for them, but I also have some algae wafers of the same brand. I might transfer the fry to the 50g once they hit 2-3 months old.

UPDATE:

The fry are doing great! I'm on the hunt for some more food for them, but they've already doubled in size. They're fat and happy, and buzzing around the tank. They all swarm up to the top for feeding now. I've counted at least 60, so I'm wondering how many will survive. I'm trying to find some food for them. I can't get fresh bbs, so I'm trying to find some frozen food that would be good for them. I'm currently feeding them egg yolks.

 

Here's a wiggler from two days ago:

Fry are officially a week old now. They've doubled in size and there are some late bloomers, but they're doing well too. They're the size of fresh free swimmers. The week old fry already have defined tails and are growing other fins. They all look great! They're fat and healthy on the egg yolks, but I got some microworms for them which are getting shipped on Saturday.

 

Sorry for the kinda crappy pictures, but it's the best my phone can do. The pictures were taken a few hours after their last meal.

The fry are doing great! Live food should be here soon, so I'm wishing for the best! these little guys are starting to grow dorsals and I've counted a total of 39 of them for 3 days straight. I originally counted that many, but was unsure. Well, I did a water change today and now I'm positive. 39 goldfish fry and a lot of them are showing huge tail spans, so these guys are gonna have some neat tails! Can't wait to see their coloration.

Well, my fiance pointed out that he thinks there's more than 39 goldfish. I know that they're active and they swim a lot, but I counted again. It looks like there's some new extremely tiny fry - like they just turned into free swimmers. Yet ... I didn't see any wigglers. Anyway, he was right. We're u to 42 now. I wonder how this is going to play out. lol

Just keep everyone full and hopefully you won't see any fry cannibalism. :) Shouldn't be hard.  

 

Thanks! I'm trying. I'm feeding them 4-6 times a day and everyone is fat and swimming around like crazy. The microworms should be here on Tuesday, so hopefully the fry will like them.

 

Other than that, I can't believe how quickly they grow! In just a week I'm seeing dorsal growth and their tails are getting huge. I can't wait to see what they'll look like at a month!

Update!

 

The goldfish fry are doing great! I culled off about 10 for deformities. I now have roughly 32 fry. I have both single tails and double tails, but everyone is doing so good. I now have two microworm cultures going along with a brine shrimp hatchery. There is one little deformed guy who I kept because he's doing great - a lot better than the other deformed fry. I'll see how he turns out, but he's a fighter! I might end up keeping him.

 

The first picture is the deformed fry and the rest are normal.

Update on fry: They will be 6 weeks old on Feb. 12th. I have an even amount of single and double tails, but it appears that the single tails are larger than the double tails. I only have two evenly large double tails, while all the others are smaller.

Goldfish fry are getting huge! I have at least one calico fry and I'm hoping to get some more. The fry have gotten upgraded to the 40gB since the turtle got put outside into the 100g pond. A lot of fry have homes stacked up, I think we're only keeping two or three fry - the calico, a singletail, and maybe another doubletail. They will be staying in the 40gB.
