Magic Emerald Shiners are a type of fish that are native to North America, specifically the Great Lakes region. They are known for their vibrant, iridescent green coloration that shimmers in the sunlight, giving them their unique name. These shiners are a popular choice for aquarium enthusiasts due to their striking appearance. In the wild, Magic Emerald Shiners inhabit freshwater lakes, rivers, and streams. They are often found near the water's surface, where they feed on small insects, crustaceans, and plant matter. These small fish typically grow to be about 2 to 3 inches in length, making them suitable for smaller aquariums.

But he added that Annie and Lou, who s been Annie s mate since last November, have been caring for all the eggs the same way, so fingers crossed we ll have all four hatch. We were thrilled when Cal Falcons first approached us in 2019 to livestream that year s hatching, which was incredibly popular with our audiences and a great use of our magnificent outdoor screen, said BAMPFA spokesperson A.
These small fish typically grow to be about 2 to 3 inches in length, making them suitable for smaller aquariums. In the aquarium setting, Magic Emerald Shiners require a well-maintained tank with clean, oxygenated water and plenty of hiding places. They are a schooling fish, so it is recommended to keep them in groups of at least five or six individuals.
Let the hatching begin! April 11 events to mark falcon babies’ arrival
The annual hatching of UC Berkeley’s baby falcons in the raptors’ nest on the Campanile will take to the big screen next Tuesday, April 11 — the giant outdoor one at the Berkeley Art Museum and Pacific Film Archive . The BAMPFA is presenting this free, day-long public event in partnership with experts from Cal Falcons .
Hatch Day 2023 begins at 9 a.m. in front of the screen near the corner of Oxford and Addison streets, where hundreds of people are expected to stop by until 7 p.m. to watch the offspring of falcon parents Annie and Lou emerge from their reddish-brown eggs. The egg hatching in the bell tower will be livestreamed on the BAMPFA screen via a webcam in the bell tower that’s directed 24//7 on the four eggs there.
Games, snacks, books and binoculars, along with an “Ask Us Anything” table, will be part of the festivities; the Berkeley Public Library also is participating.
Also on Tuesday, a livestreamed Q&A with Cal Falcons biologists Sean Peterson and Lynn Schofield will start at 2 p.m. and give Berkeley falcons fans around the world the chance to ask their questions as they simultaneously watch activity in the nest.

Peterson said the first egg likely will hatch “either very late April 10 or early on the morning of April 11. Typically, all the eggs hatch within about 48 hours. The first three eggs are usually closest together, followed by the fourth.”
Not all the eggs that Annie has laid annually since she arrived on campus in late 2016 have hatched. She usually produces four eggs a year, and typically one fails to open, said Peterson.
“It’s a little strange that she’s never had all her eggs hatch before,” he added. “It could just be random chance, or it could be some characteristic unique to Annie. It’s really hard to say.”
But he added that Annie and Lou, who’s been Annie’s mate since last November, “have been caring for all the eggs the same way, so fingers crossed we’ll have all four hatch.” Annie lost longtime mate Grinnell in March 2022, and then a second mate, Alden, last fall.

The April 11 BAMPFA-Cal Falcons event is the second one to take place at the outdoor screen on Addison Street. The first time was in 2019, when a whopping 700 spectators showed up. But the following year, the pandemic hit.
“We were thrilled when Cal Falcons first approached us in 2019 to livestream that year’s hatching, which was incredibly popular with our audiences and a great use of our magnificent outdoor screen,” said BAMPFA spokesperson A.J. Fox. “COVID put a crimp in our plans after that, but we’re delighted to reprise the partnership this year.”
Last year, a Hatch Day event was held on campus near the Valley Life Sciences Building, but without a livestreamed option for attendees to watch the hatching together. Still, “hundreds of people came and went,” said Mary Malec, a Cal Falcons raptor expert.

This year, Malec and other members of Cal Falcons, wearing Cal Falcons T-shirts, will staff an information table outside the BAMPFA and hand out stickers and other freebies. Malec added that the Berkeley Public Library will provide “games and books and things to color” from 11 a.m. to 3 p.m.
Cal Falcons provides the library with a few sets of binoculars a year that can be loaned, along with bird identification books, to people who want to search for and learn more about birds in the Bay Area, she said.
After the eggs hatch, Peterson said the chicks will depend on Annie and Lou to incubate them for about 10 days, so they can stay warm.

“Lou will still be the primary hunter,” said Peterson. “Annie won’t likely start to hunt for around three weeks or so. With past partners, she has performed the lion’s share of feeding the chicks, so we’ll see if that trend holds up again.”
The chicks’ first meal typically happens within 12 hours of hatching, and they’re fed a strict diet of meat. Annie will “very carefully pick small portions of meat off of prey to give to the chicks,” said Peterson.
The most likely timing for the chicks to begin flying off the Campanile is around May 21, he said, adding that “all the chicks likely will have flown by May 28,” with the males frequently fledging a few days before the females.
CO-PARENTING
It is not uncommon for two broodies to sit on one clutch of eggs or for two broodies to raise chicks together.
A varied diet consisting of high-quality flakes, pellets, and live or frozen foods, such as brine shrimp or daphnia, should be provided to ensure their nutritional needs are met. One of the most captivating features of Magic Emerald Shiners is their ability to change their coloration depending on their environment and mood. When they are relaxed and comfortable, their shimmering green color is most prominent. However, when they feel stressed or threatened, their colors may darken to a more dull shade. Breeding Magic Emerald Shiners in captivity can be quite challenging, as they require specific conditions to successfully reproduce. Providing a separate breeding tank with ample vegetation and hiding spots can aid in their breeding process. Additionally, mimicking the natural seasonal changes in temperature and lighting conditions can help stimulate breeding behaviors. Overall, Magic Emerald Shiners are a visually striking and fascinating fish species that can add a vibrant touch to any aquarium. However, their care requirements and breeding challenges make them more suitable for experienced aquarium hobbyists. With proper care and attention, these beautiful fish can thrive and provide endless enjoyment for their owners..
Reviews for "The conservation status of magic emerald shiners"
1. Ellie - 2/5 stars - The "Magic Emerald Shiners" were a total disappointment for me. I had heard so much hype about how these lures attract massive fish, but they didn't work for me at all. I tried using them in different water conditions and at different times of the day, but I didn't even get a single bite. I ended up switching to my old reliable lures and had much better luck. I feel like I wasted my money on these so-called "magic" lures.
2. Jake - 1/5 stars - I can't express how disappointed I am with the "Magic Emerald Shiners". They look great and the packaging got me excited to try them out, but that's where the magic ended. I used these lures in multiple fishing trips, and not once did they live up to their claims. The fish completely ignored them, and I had to resort to my tried and tested lures to actually catch anything. Save your money and don't fall for the marketing gimmick of these supposed magic lures.
3. Sarah - 2/5 stars - I had high hopes for the "Magic Emerald Shiners", but they failed to deliver. The colors and design are attractive, but that's about it. I found that the fish were not interested in these lures at all. I tried different retrieval techniques and even let them sit in the water, but nothing seemed to work. It was frustrating to see other anglers catching fish left and right while I struggled with these supposed magic lures. I won't be using them again.
4. Mike - 2/5 stars - I wouldn't recommend the "Magic Emerald Shiners" to any serious angler. These lures may look flashy, but they are far from magical when it comes to catching fish. I took them out on a couple of fishing trips, and I barely had any bites. The fish seemed completely uninterested and passed by these lures without a second glance. Don't waste your time and money on these gimmicky lures. Stick to the proven ones that actually work.
