#Rhodeus ocellatus

[aquariuminfobureau]

In past days, it was possible to obtain, at least for aquarists in the UK, at least two species of bitterling, Bitterling, which are cyprinids of the genus Rhodeus, are of interest for their fascinating life cycle, one that is based on depositing its eggs within a freshwater mussel, as a protected environment for the growth of its offspring. Sadly the bivalve is difficult to care for in aquaria, and almost always dies. So it is very difficult to breed bitterlings in the home aquarium, and it should not be attempted by those unable to respect and care for the mussel, that must live with the breeding fish. Bitterling possess a very large, tubular ovipositor, for the purpose of positioning their eggs inside the living mussel. Indeed the size of this structure, relative to the length of the bitterling, is visually striking.

One of the species traded, was R. ocellatus, the rosy species from East Asia. In fact the species once had a much smaller range, for it was once restricted entirely to the island of Taiwan. Centuries ago, this species was introduced to mainland China, as well as Korea and Japan. Since those days, populations have invasively colonised quite far flung locations, but the latitudinal range of this species in Asia, ought to inform us as to its tolerances. For it is established in Beijing just as it is in Hong Kong, although the latitude of Beijing suffers far more severe winters.

Rosy bitterlings are common in vegetated farm ponds and irrigation channels, and they grow to around 9 centimeters, or under 4 inches long. These species display sexual dimorphism, with the females growing to only a mere 2/3 of the length of their male counterparts. Originally this species preferred lakes, natural ponds, and sufficiently slow moving rivers. But now it is quite synanthropic, and is considered a nuisance on fish farms, where they are believed to compete with the juveniles of the cultivated species.

Rosy bitterlings appreciate a rather neutral pH, and a temperture range suited for a warm temperate to subtropical fish. 28 degrees centigrade might be regarded as a good upper limit duriǹg the summer season, dropping to a few degrees below zero, in the wintertime. Although this fish has become established long ago, in some regions where the winter air temperature is often below freezing, most of its populations do not. And it is unnecessary to expose this fish, to such low winter temperatures. Although a winter drop in temperature, is natural for these bitterlings.

When intending to accommodate R. ocellatus, their aquarium should be well planted, and the provided substrate fine, to reflect their natural habitat. Other peaceful fish can cohabit with bitterlings, although they will need to share its requirements as a non-tropical species. Like a great many cyprinids, R. ocellatus naturally form schools with their conspecifics. Their diet is recorded in the wild, to be omnivorous with a vegetarian tilt, including both algal and small arthropod components, but diatoms are their primary food source in the wild.

Animal Crossing Fish - Explained #33

Brought to you by a marine biologist who got really confused with this one...

Fish I’ve Covered: Click Here

So, yeah, today’s fish gave me way more trouble than I thought it would. See, when you think of an animal, like “tiger”, I’m sure you don’t immediately realize that there are a number of species under that umbrella term. Even animals as iconic as elephants, or as common as hamsters have multiple species that can look VERY different from each other. And that’s kind of how Animal Crossing treats a lot of its fish. They say “tuna” and you’re none the wiser. Most people don’t realize there are many species of tuna and even multiple species of bluefin tuna. But, because I get paid to identify marine fish, it’s really no trouble for me on the marine fish. But these freshwater guys...heh, to be honest, I’m still not really sure which Bitterling AC:NH intended, if they intended anything in the first place:

For us in the Northern Hemisphere, Bitterling are available from November until March, so we had to skip to it to catch this little guy when the game came out. Bitterling are small fish native to rivers in Asia. In Japan, there are multiple species of native and non-native Bitterling and that’s where my trouble started today.

So, just like lots of fish we’ve already covered, Bitterling are in Family: Cyprinidae, and by the end of my coverage of these fish, you’ll know all about it. Cyprinids are the most numerous of freshwater fish, with lots of species, some of them important to people, like carp, koi, and goldfish. For the Bitterling, it’s important to people who “micro-fish”, or who fish for really small species of fish. So, in essence, this is a sport fish, but it’s targeted for its beautiful colors rather than the fight it can give (which is probably like none). In Japan, they are called “tanago”.  In fact, tanago fishing is the smallest scale fishing in the world, according to some of my sources. So, there ya go - I guess that���s why it’s in the game.

But IDing this tanago to species was a pain. Now, I’ve admitted before that for these freshwater species, I look to the Animal Crossing Wiki for help, but this time, like with the loach, I didn’t agree with their Japanese Bitterling (Acheilognathus melanogaster), mostly because the body shape nor the coloration was correct. In fact, the wiki gives that species, but then links to an entirely different genus, which actually turned out to be more correct, Rhodeus. Now, do we know how to read binomial names? Let’s go over it real fast:

When you say an animal’s binomial name, what you’re telling someone is the Genus and species names of that animal (and yes, they must be italicized with Genus capitalized and species lowercase...I try to do my best with that). For example: 

Homo sapiens, in which “Homo” is the Genus and “sapiens” is the species. 

Again, Tyrannosaurus rex, in which “Tyrannosaurus” is the Genus, and “rex” is the species. (lmao, this one blew my husband’s mind)

So, for our Bitterling on the wiki,  “Acheilognathus”  is the Genus and “melanogaster” is the species. And it’s just wrong IMO. Instead, our Bitterling belong is Rhodeus, a group of Bitterlings who have deeper bodies. Now, unfortunately, this is where the surety ends. This could either be the Rosy Bitterling (Rhodeus ocellatus) or the Japanese Rosy Bitterling (Rhodeus smithii) OR IT ACTUALLY COULD BE A HYBRID OF THE TWO:

Picture from this site.

Both species mingle and interbreed within rivers and streams in Japan after the regular Rosy was accidentally introduced in 1942 from mainland China. Since then, the Japanese Rosy Bitterling (JRB) has become rarer and rarer as the regular Rosy takes over and they make more hybrids. The JRB is now critically endangered because of this and I doubt there’s much anyone can really do...it’ll probably go silently extinct. Now, I’d love to say for sure that AC:NH chose the JRB because it’d be nice to immortalize an animal going extinct, or that it’s definitely the Rosy Bitterling because if you go micro fishing in Japan for tanago, this is probably what you’ll get. But I can’t say either of those things for sure, because both these fish kinda look the same and the same as the AC:NH Bitterling when in breeding colors. The fact that they hybridize so easily also kinda threw a wrench into my research, and I’ve thrown up my hands. It could be either...it really could. 

And there you have it. Fascinating stuff, no?
