Growth rate of CRS, Tigers, etc

[ravensgate]

Can folks list their experiences with growth rates on the following, this is from time of hatch to breeding maturity

CRS/CBS/Goldens

Taiwan Bees

Tibees

Tigers (OEBT, BTOE, Super, Regular, etc)

Coming from neo experience I must admit my mind is blown as to how slow the growth is on these particular shrimp. I have a 10 week old baby OEBT that's just now hit a full 1/4". It also looks like growth of CBS is slower than CRS (in same tank) but my experience is limited on these as of right now and furthermore, it doesn't make much sense in my head why they would grow slower than CRS.

Also if you don't mind, please list the normal 'average' temperature you keep your tanks at. I know warmer temps can speed growth rates of neos, not completely sure on others. Thanks in advance!

Oh man, this is a good question and you'll never get a satisfying answer, lol.

So many factors involved that not even members of the same clutch develop at the same rate.


But, in my tanks, at 72f, and fed daily, crs and CBS take 4-6 weeks to get to 1/4 inch, and then another 2-3 months to breed. Same for tigers and taiwan bee.

Cardinal shrimp are much faster, they grow to breeding size in less than 3 months.

Haha, I'm never satisfied! LOL! Seriously, I know there are 100 factors from diet, temp, genetics, and on and on and on I just wanted to make sure I wasn't losing my mind and these DO grow way slower than neos.

Those rates sound about on track with what I was thinking. I just remember going 'Whaaaa???' when I got some OEBT from Speedie and they were a good size and I asked how old they were and he said they were 6-8 months old and would be ready to breed in another 2-3 molts. Seems like they spend most of their lives just trying to get to adulthood. Doesn't leave a lot of room for too many clutches I wouldn't think

[GeToChKn]

For an easy answer, yes, they grow slower than neo's. lol

Keep your nitrates and phosphates in check too, both affect growth

Nitrates are 0 in both tanks. What do phosphates need to be?

0 would be best, although if nitrates are 0, and you're not dosing ferts, phosphates are probably already low and they tend to go hand in hand from overrfeeding, not cleaning, not changing water, etc.

and a < raspberry > back at ya. lol.

I was just thinking the same question. My new Taiwan BKKs are all growing at different rates. The first 3 that came from my BKK mamma are big at 6 weeks old. However the 3 week old ones from my BB mamma x BKK are all different sizes. They are all eating the same food in the same breeder box so why are some bigger than others? Some are almost double in size...don't understand.

[sbarbee54]

I have always seen 4-5 months with Tigers and CRS/CBS as well as my TB. My neos on the other hand 2 months at 76 temp.

I keep nitrates at 0 and phos at 0.


I think tigers would do it faster but having to keep them in lower temps slows them down.

My Taiwans are the same way pinoyghost2. Some of them are now more than twice the size of others, even though they were all roughly the same size when I got them.

[PuddlesAqua]

As for being different sizes, they're not clones of each other. They have different dna and will grow at different rates. Maybe your small shrimp are just the runts of the litter.

[pinoyghost2]

there all siblings so yes they do have the same dna...but your right, maybe they don't eat as fast as some of the others, so don't grow as fast...hopefully they will catch up.

[sbarbee54]

Or as most TB bought from source where not all hatched at the same time so could just be in differing maturities when you get them... Now with new babies I find that females do grow a little faster, but that is because they get bigger. So in true aspect they tend to grow at the same rate as I have seen

[pinoyghost2]

Hmmnn, well in that case I have one mother of a BKK cause its huge! She's obviously gonna be one of my new breeders.

When I got all of my BKKs, they were all the same size, and the female
(mother of that baby I mentioned above) isn't any bigger than any of the males. In fact I find it very difficult with these Taiwans to be able to tell what sex they are even as adults....they all look the same to me.

I only noticed this female was berried one day because it looked more rounded on the bottom, otherwise I would have totally missed it. Not like other shrimps which you can usually tell when their berried.

My BB female didn't even look berried until she was about 2 weeks then I noticed she was showing something different under her shell. Maybe their shells are more dense and that makes it more difficult to see the eggs from outside unless you have them under a specific light.
