Celestial Pearl Danio Hybrid?

[lilsd]

Went to my LFS yesterday and they had a nearly empty tank with 6 lonely looking CPDs in it. I’ve been thinking about getting a few CPDs for awhile now, and they were on sale and calling my name, so I took them home. After acclimating and adding them to my tank, I was watching them, and there was just something a little bit “different” about them. I haven’t had CPDs before, but did some googling and it seems I have CPD x dwarf emerald rasbora hybrids, which look slightly different. Has anyone else seen these in stores advertised as CPD? I don’t plan to breed them, I just got them to enjoy. Their care requirements are still the same and they’re still pretty, and they are healthy so I’ve got no problem with keeping them, it was just an interesting surprise and I’m curious if this is a common issue with this species.

Looks like a CPD to me. I have CPDs in the same tank as dwarf emerald raspora. See pic.

The start of the caudal fin is different. The black spot is present on the CPDS a trait known to the Emeralds.

Maybe my OCD is showing but if you look at mine, they don’t have stripes on their fins/tails, and they all have the bold dot at the base of the tail that you see in the emerald rasbora, which I don’t see in any photos of true CPDs

Thanks. Good pick up. I learned something.

Ive just had a look on Reddit and have seen many posts showing the same patterns. Two OP's claim they bought them listed as CPD x EDR hybrids

Very few people read our discussions, but there is food for thought here. Danio margaritus, the CPD, is a "Data Deficient" fish on the red list for endangered fish. In effect, there is no proof of its status either way. There are rumours about limited wild numbers though, and the ones we get are captive bred.

It's a species that could become extinct in the wild, with a limited range and human pressures on it.

So if a couple of fishfarms create hybrids, and don't label them, this easily bred (self breeding in a good set up) fish could be replaced by hybrids. Most hobbyists wouldn't know any better, and most hobbyists don't care about biodiversity. If it's gone in nature, by sloppy breeding and careless marketing, it could be gone in the hobby as well. We'd have something vaguely like it, for as long as hybridization didn't wash out its colours.

Both species are attractive and interesting in their own right, and I would hate to see them thrown into a soup pot to come out as a neither here nor there single fish product. If you have any doubts about whether you have a cross, don't breed and distribute it. If I saw a cross labelled as such, I wouldn't buy it.

If I liked the fish and had a group of unhybridized ones, I'd breed them and distribute them. We are consumers, and we have a misguided faith in the fish farms to supply us with the fish we love. When I see things like this, I see a misplaced confidence in the industry.


Those little species are marvels, and I'd like to see aquarists in 2124 being able to say the same.

Are you now thinking yours could hybridise in the same tank?

If that's a question for me - I don't keep them. If I did, I would have them in single species tanks, because they breed so easily and a giant 'herd' would be cool to watch.

I never keep fish I think can hybridize together. That's why we buy more tanks!

My CPDs haven’t bred in the two years they have been with me. I may have gotten only one sex. They are all as colorful as Amazon parrots so I assume all males.

Sorry, I misread. It was Gwand who has them together, not you!

Yes it was me who made the boo boo. Same genus but different species. I did not think they could breed successfully. There has been no successful spawning or even egg deposits so far. If hybrids are created they will live and die in this tank. There is no chance any would enter the real water world.
