The Black Thai Ranchu: "Boxerheads"

I recently purchased one of these fish and after a lot of research was extremely surprised at the amount of distinctive traits this strain has. Like Kirin, Edo Nishiki, Bluebelly and other types of specific SVR the black thai ranchu is its own creature.

Here is a quick compilation for anyone who owns them or is thinking to buy and wanted to read a quick summary sheet of what I've learned!

ORIGIN: Thailand

This fish was developed from Thai SVR and lionheads added on occasion. This is about where sources stop agreeing concerning origin of the strain. At this point in time however everyone agrees that the Thai have produced the best, deepest black with the firmest hold for colour of the black SVR. Chinese SVR tend to colour red, gold/bronze or white up the belly with age. Like all black fish natural sunlight will help the black but there are many Thai Black Ranchu in tanks who have not lost their colour. In Thailand it is graded according to SVR standards and shown under a class called "Tamid".

SIZE:

Instead of the 6-8/8-10 inches most ranchu are said to grow to many breeders who groom this fish state it's tendency to be 5-7 inches when grown on average. With their considerable rotund girth and weight don't expect this to make a difference with bioload!

COLOUR/CONFORMATION:

Black is the only acceptable colour. The black is matte, and deep. When a scale goes missing, underneath is usually a bronze/gold colour (Some farms are rumored to keep these fish in ponds with mirrored bottoms to help deepen and maintain the black!). The best specimens will be black even under the head and belly with no lightening of tone. These fish have very small eyes, broad, strong heads and the wen covers the eyes. Most fish are blind, and show quality fish are expected to have this wen coverage. The wen is not trimmed. All other grading, minor and major faults are assigned according to the SVR standard.

NOTES:

All in all a beautiful fish, with its own distinctive traits, pros and cons. Most are said to be vigorous eaters and foragers, having no issues competing with other SVR for food despite poor sight/no sight. Standard grooming practice is a high blood worm diet with a good pellet, and crystal clean water as well (to promote wen and girth). Ocassionally difficult to reproduce this black through black to black pairing.

Good post! I have a Thai black svr and I love him, they are indeed tricky to reproduce sometimes. However links to other forums are not allowed on kokos, so it's best if your remove them. :)

Thank you for making me aware, I've messaged a mod to remove the 3 links to other forums.

They are so neat aren't they?!

Sigh. :heart I love them.

I didn't know until I saw one in person, definitely [emoji173] at first sight!

Interesting!

Thanks! [emoji106]

There are a lot of new info for me. Thank you for sharing Amy!

No problem, I'm just happy some of this was new to others besides just me lol!

Thanks, Amy. I think they are beautiful.

Glad to share! I'm happy there are other fans out there too, they are an...interesting looking fish :P

Beautiful fishy! :) Congratulations!

Thanks! My other half and I decided that she looks like a bulldog and a salamander had a fish baby. I'm fairly sure he meant it as a compliment.

They are a stunning fish. Thanks for the info

I agree, I never thought a fish could be so DARK. And happy you liked it [emoji4]

This is my 1yr old Thai SVR. He's a very very pretty fish.

Wow great grooming! Look at the head on that one, such a great specimen! Well done on your part.

Anybody else have black thai SVR? Let's see Em!

Beautiful fish! I think breeding high quality goldfish is not an easy thing and I appreciate those who care enough to do so, but the idea that a fish will most likely go blind due to careful breeding is something I have to get use to.

That's part of why I thought I should post this. I had no clue until after I got her home that there was a type of ranchu like this, that went blind almost inevitably due to wen growth. It scared me at first, and I felt a bit better after I realised it was normal but I still feel kinda bad for the poor girl. It did prompt me to do some tank redecorating :)

Thank you! He comes from ECR lines so he has genetics on his side as well. He's a very well balanced fish and his black is only getting darker as he ages.

If it is any consolation my black ranchu seems to have no issues with sight. He is the first one to food the second it hits the water. Most telescopes have major sight issues but most people tend to look past that. As long as the fish is living a good quality life ya know? :)

I'm hoping as mine grows the wen won't be such a problem. She's adapted very well in just the week she's been in the main tank.

And good news I got the go ahead from Koko to leave the links section standing as is. In lieu of the nature of information, she thought it would be valuable to have it available for others :)

I know! Fortunately blind goldfish can get around and find food just fine, but still. I feel kinda bad for them when the wen covers their eyes completely.

This is fascinating. Lucky you for finding such a fish! The black goldfish I've bought have always turned orange/red.

It was definitely a lucky find, they tend to hold black so well. So well in fact that I'm having to wait until I purchase much stronger lighting or he gets much larger to be able to determine if there even is an eye under there lol or his face shape etc. On a positive note breeding tubercules show up well on black :) it's a boy!
