I have come to the conclusion that when Reticulata are VERY new born (weeks maybe months), they have a very distinct grid-lock soccer ball type pattern that they eventually grow out of.. very similar to how P14s are born a brown pup which very much looks like Scobina, and over time develops into a black ray.

I think that this pattern will change over time with maturity, but the rays disc will fail to grow due to lack of nutrition and/or stress.

I have 5 very tiny juvenile retics right now, 3 of them have a reticulated pattern while 2 of them show this juvenile pattern.

1 Reticulata from my first batch of 3 also displayed this pattern, but it broke up within a month or so and became a normal reticulated pattern.

I've observed that some of the body features (such as eyes, spiracles, etc) are larger one the retics with the developed pattern, but the overall disc size is not indicative of amount of time since birth. In other words, the rays have the same disc size but they are different ages and you can tell due to the development of the juvenile pattern and the seemingly larger overall body structure. This could also be a sign of varying genetics and hybridization..

Perhaps the retics that are born with an already in-tact reticulated pattern contain the genetics of another ray, which could determine max size, growth rate, etc.. Perhaps the retics that are born with the soccer-ball type pattern contain the genetics of another ray..


Just thought this is an interesting note.. and if anyone sees these rays with "special" labeling as a different or rare species, keep in mind they are very young and hard to care for at that stage..

Heres some pix as examples of the juvenile stage.. first pic is my "new born" retic, and the last 3 pics are from a german breeder who birthed those pups from a pair of 6-7" retics..


Thoughts?

Discussion?

Thanks for looking.. going to make an interesting thread on 'disc rot' as well.. seems like a few of these guys have it.. a fungus? We will find out if salt and good water quality will fix it!

Heres a 2 month comparison of the same ray..

In the first pic it's just starting to break up.. in the 2nd one you can definitely make out the "webbed" floral pattern.

excuse my photography skills but I think you can tell the change in pattern.. it's amazing how fast it breaks up and changes.

wow i definately see the difference in the patterns. the update kinda makes it looks like some kind of flower ray.....lol you got me looking at my retics and my darkest retic is showing the exact pattern change as yours. it seems like every week i have trouble telling which of my retics are males and the female because they change their color so often. when i first got them they were all very dark and i was only able to tell by looking at their bellies and the female was the second darkest retic but now she is the darkest retic. all 4 of my retics were bought all at once from the same lfs but yet all look every different from one another. the water quality is perfect temp is currently at 78 (thats the temp they seem most active) and water changes are done every other day. is the color change and pattern change a sign of stress or natural/genetics?
 
I think it's natural.. I don't know? We will find out!

I am going to take notes on all my retics.. ie: tail structure, pattern development, growth, etc..

I've noticed one of my reticulata has way more spikes on it's tail, than the other.. They also had different developing patterns as juvies.. ? Could that hint towards genetics?

i too will try and document any changes hopefully thru pictures.
 
the pattern might help the pups survive in the wild... help blend in better
