r/Rainbowfish

slow mo footage from Litchfield NP in the Northern Territory.

showcasing these contrast between these two beautiful species. they are just hanging out here, still trying to capture decent footage of when they are sparring, which they do very regularly and intensely.

relatively closely related among rainbowfish, and found within maybe 100kms of each other in the Kimberley, although Melanotaenia nigrans is distributed throughout much of northern Australia, while Melanotaenia pygmaea is limited to a few tributaries of the Prince Regent River.

this is only a small area of their tank (still not all that densely planted), it is easier to capture footage against this background. both species are very suited to densely planted tanks, however only Melanotaenia nigrans is found amongst significant aquatic vegetation in the wild.

Only have had them a few days and they’re already perking up nicely.

10 fish sold/given away. After breeding and taking care of the fish selling is the least fun part of the process. But you just can’t keep’em all,atleast I can still enjoy watching this for now

These guys are pretty rare in the hobby! Threadfin rainbowfish or Iriatherina werneri.

The males will square off like this to establish dominance. The presence of females increases their sparring/brightness of display colors, but mine do it even without.

I hope I’ll be able to find some females someday and may potentially try breeding them simply so others can enjoy this underrated nano rainbowfish.

Over the past few weeks, Sam has received numerous questions via email, Facebook, Reddit, and Instagram about the care and husbandry of hillstream loaches, gobies, and other stock we carry.

Many inquire about which species are compatible for tank living, quarantine procedures, proper water change techniques, the best food for HSK animals, tank setup, and recommended filters, among other topics.

We believe a live YouTube Q&A would be very helpful for our customers and potential customers who are unsure about how to care for our wonderful little animals.

Of course, Sam welcomes any and all questions, and we would love to reach a broader audience, especially those unfamiliar with HSK and the incredible stock we offer to U.S. aquarists.

Based on everyone's feedback, we will decide whether to schedule a live Q&A sometime next week.

Thoughts? Good idea? Would you be part of the live?

Share this post with any aquarists, aspiring aquarists, or anyone interested in learning more from Sam about the stock available on our website.: https://hillstreamkingdom.com

My Dwarf Neon Rainbowfish has been gasping for air for the last couple of days, heavy breathing and sluggish behavior. All the other fish are fine, what could it be?

15 Pseudomugil gertrudae have arrived today and are already enjoying the waterflow. Very nimble and pretty hard to film!
