Shrimpmaster Posted September 8, 2015 Report Share Posted September 8, 2015 My Neocardina grows at least 2 times faster than my Cardina and maybe 3 times faster than my TWB. It's nothing special, we all know this is very common, but does anyone know why? Just genes, that's it? Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted September 9, 2015 Report Share Posted September 9, 2015 Yeah. Different species different genes. Louie 1 Quote Link to comment Share on other sites More sharing options...
Shrimpmaster Posted January 23, 2016 Author Report Share Posted January 23, 2016 I'll keep studying them about this subject and I notice something else. They eat at least twice as fast the Catappa leafs I put into their tank. Comparing to a Cardina group of same size. In some tanks they have to get started with them and in the neo tank, it's already stripped bare to the veins. Is it possible they have a higher metabolism or is this a weird hypothesis?

nuri Posted January 23, 2016 Report Share Posted January 23, 2016 what i noticed is 1. the neo's are way more active then caridina shrimps. they constantly are hunting for micro organisms. this will lead to faster growth for neo's 2. baby neo shrimps does not stay at 1 specific location (they swim all over the tank) my baby taiwan bees are always at the same location until they are few weeks old then they start to explore...... that is why baby taiwan bees have lower survival rate then my neo's, they don't explore to find food........

Shrimpmaster Posted January 23, 2016 Author Report Share Posted January 23, 2016 Indeed. 2nd point is also a good one! I did notice that, but never paid attention to it. But they are swimming a lot these little fellas. According to all this, you could expect them to live shorter too. But that is something I can't say at this moment. Anyone?

dreamer_yoyo Posted March 6, 2016 Report Share Posted March 6, 2016 Food sourceas well. Neocardina are not picky when eating. Quote Link to comment Share on other sites More sharing options...
DETAquarium Posted March 7, 2016 Report Share Posted March 7, 2016 Excellent topic. I always wondered the "Why" behind this, as I have switched from all Neocaridina to Caridina species I definitely have noticed this. I have noticed this even more so when breeding Taiwan Bees to Tigers and back. The Tibee and Taitibee offspring grow so much faster in comparison to the Taiwan Bee shrimplets. My guess is primarily genes, but that is a great point that Nuri made regarding roaming shrimplets. Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...

My guess is primarily genes, but that is a great point that Nuri made regarding roaming shrimplets. Notice the same thing. My two taitbee's from mayphly released babies within the same week my BKK did. The father or fathers of all three shrimp was a BKK and possibly a BTOE because I have a baby that is dark blue with one white stripe in the middle and two white dots on the tail and has orange eyes, but back to my point, the taitbee babies are much larger than the BKK babies and ages are within days of each other.

Shrimpmaster Posted March 8, 2016 Author Report Share Posted March 8, 2016 According to hybrids, the grow faster an bigger among all animals if i'm correct. Like the crossbreed of a lion and a tiger: But this is applied to hybrids, but does not explain the difference between neo and cardina. But the observations already posted above seem te be very obvious explanations. Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted March 8, 2016 Report Share Posted March 8, 2016 My neos still grow faster than card crosses though. heh Quote Link to comment Share on other sites More sharing options...
Jomes Posted March 9, 2016 Report Share Posted March 9, 2016 I would guess that neos are just genetically hardwired for faster growth. Different genes for different means! Hybrid vigor could account for faster growth in Tibee shrimplets, but it is not universal in all hybrid crosses. In regards to ligers, their large size is the result of a run away growth gene that only manifests in male lion x female tiger cosses. Tigons (male tiger x female lion) do not grow larger than either parent species. Tigons also suffer from a host of medical problems that would be hard to describe as "vigor."

Learned something today, tnx Back to the topic. I also notice people keep neocardina on much higher temperatures than other shrimp. This should also speedup metabolisme and growth right?

pucksr Posted March 23, 2016 Report Share Posted March 23, 2016 Yeah, but temp doesn't explain it. Babaulti are high temp too, but slow growing. You are confusing yourself. The "why" is genetics. Neos simply have the genes to grow faster. Everything else is "How?". Many answers: more voracious eaters, faster metabolism, etc Sent from my Nexus 5X using Tapatalk Mr. F 1 Quote Link to comment Share on other sites More sharing options...
Shrimpmaster Posted March 23, 2016 Author Report Share Posted March 23, 2016 Good point, thanks. The 'why' and 'how' as a good distinction. I found an even more 'agressive' growing shrimp, the so called 'mini-japonica'. I've seen tanks where they were crawling 5 layers thick, bad water quality and still so much females with eggs and keep on breeding. Also a good example of the difference in growing and breeding compared to Cardina. Quote Link to comment Share on other sites More sharing options...
oem Posted March 23, 2016 Report Share Posted March 23, 2016 Just as it is with all life, genetics is number one, with environment also playing a part. Adapt, and offspring will survive. A constant process in life as our environment changes. We can manipulate the environment of animals for our benefit over time. Think water parameters.
