Question on Red Hook Silver dollar Varieties????
- Thread starter Chefken
- Start date
I love them both....very fast growers! Thanks for offering to take them off my hands.....I just like to know exactly whats in my tanks. First my Red Hook suddenly developed spots....then i realized my "Blue Hook" was without bars....I bought them both as Red Hooks so I was a little confused. I searched threads here and elsewhere and found out about "Luna" Red Hooks but could find nothing about my big guy with blue fins.snake8myelbo;4880138;4880138 said:
I still have not heard from anyone else who has ever seen one!
Sometimes when a blue or redhook is stressed the black bar caqn fade/ I have two thin barred red hooks myleus scrhomburgi (wrong spelling). The black bar will sometimes fade when the lights are on or they are stressed. My neice has a shoal of the blue hooks and their black bar is wider and they are more of a larger pacu-like characin. You may have some hybrid.
Thanks....I am thinking hybrid. This guy is dominant in the shoal. I doubt stress is driving his bars away as I have had it for months and it has never had any bars. Grows 10x faster than my standard SD in the shoal as well.....Hybrid vigor??Allan01230;4882609;4882609 said:
Any Myleus rubripinnis - Red Hook will become this so called Luna. They develop the spots with age and as they get older more and more spots develop and their chests get nice and red as well in the males. Wait a couple more years and it will look much better yet.
Thanks for the info! Now do you know anything about my blue guy???CanadaPleco;4953766;4953766 said:

One thing I do know that nobody has mentioned is that both of your hooks are female.
You appear to have a Myleus rhomboidalis. I don't see any hybrid in her. She is big and about the same size as my largest at 6-7" tl.
I am not familiar with the term luna.
All my female Myleus rubripinnis look just like yours and get the spots for periods of time also.
The M. Schomburgki wide bars get much larger. Most my big guys are 10 to 12" with a couple topping out at 14".
You can see some of these fish in the 15,000 video in my signature.
You have nice fish and a wild collection in your 150g.
Thank you for the info and compliments!! i was hoping someone with real experience would eventually chime in.arapaimag;4966693;4966693 said:
Too many keep SD types as dithers without knowing anything about them at all!! You have made me a bit confused though!
Is Myleus Rhomboidalis Pacu??? you refer to mine as large....as big as your largest at 7"......The record M. Rhomboidalis according to research is 25kg! Is this a monster SD type or not?? Very interesting to find out they are both female. I must find a male Red Hook!! Thanks again!! Ken
I wiil agree with aripaimag that M. rhomboidalis is a good candidate and you definately have females, however an exact id is very difficult. The taxonomy of these fish is somewhat in confusion and a revision and update is needed. I have seen many types of " red hooks" in the fish markets in Iquitos and one thing for sure is that color is extremely variable amonst them. Some of the means to classify these fish is by fin ray counts and serrae on the keel. If you do this while the fish is alive you will need an eye transplant.
