Most animals on Earth do not take care of their offspring. It’s just too much work, honestly. No, really, it is. Feeding and protecting tiny versions of yourself for weeks to years takes resources that are hard to come by, like food, shelter, and energy. Parental care is an evolutionary trade-off that will affect litter size and how well-developed the offspring are. Fish usually provide no parental care to their babies, as a rule of thumb. Today’s fish, the Angelfish, does, though!

It’s fun to catch these guy in Animal Crossing. They are pretty, unique, and honestly, I never get sick of seeing them while trying to get the rarer fish. Under a small shadow, just fish during its active hours and you’ll eventually get it. When you donate to the museum, they are put into that “aquarium” tank in the freshwater section with the other hobby-aquarium fish, like the Neon Tetra and Goldfish. And that’s accurate, because this species, the Freshwater Angelfish (Pterophyllum scalare) is popular with hobbyists the world over.

Native to the Amazon River basin and its tributaries, the Freshwater Angelfish lives in slow-moving streams and floodplains within its range. Those gorgeous stripes it has are actually its camouflage, allowing it to hide within the shadows and stems of submerged plants. 

Above I mentioned that the Freshwater Angelfish takes care of its young; in the wild and in the home aquarium, Angelfish will aggressively defend their babies against any other fish that gets too close for up to two months after the young hatch from their eggs, which the parents lay under plant roots and leaves. Although parental care is fairly rare in fish, it’s actually one of the hallmarks of the Family Cichlidae, the Cichlids, for which Angelfish belong. 

But besides that family, you really don’t see parental care in fish. As we’ve covered before, most bony fish (basically anything that isn’t a shark in ACNH, for reference) are either broadcast spawners, in which everyone comes together and spews out their eggs and sperm into the water to find each other and get taken by the current, or they lay their eggs somewhere and leave (or die, like salmon). The strategy is ultimately to make as many babies as possible, which overwhelms predators - they can’t possibly eat them all! Lots of species of fish will have MILLIONS of babies per spawning season, per female, which ensures that some will make it to adulthood. But that comes with a cost - to make that many babies, the babies themselves will be low-quality. Even after hatching, the babies are called “larvae” because they still have so much growing to do. Even for giants like Bluefin Tuna, their babies are just a few millimeters long.

^What fish larvae look like. 

And most fish have no concept of what fish larvae belong to them - adults will gladly eat baby fish, which means, in the aquatic environment, cannibalism is accidental, but not uncommon at all. It also means small filter feeders, like anchovy, are totally capable of eating their predators, and they do all the time. Stuff like this is what makes aquatic biology so different than terrestrial biology with similarly-sized animals. Saying an anchovy can eat a bluefin tuna, even as a larva, is nuts when you realize that’s analogous to saying “a zebra ate a lion cub”. It’s unheard of for us and other animals that put all their effort into parental care instead, giving birth or hatching just a few big, well-developed babies and then caring for them for a long time. That strategy ensures that all babies make it to adulthood, but at the cost of having more at a time. And that’s the trade-off - quantity or quality? 

And that’s what is really cool about the Angelfish. Their babies are still tiny larvae, but the adults protect them as best they can while the babies figure out how to get food on their own for two months. Even though that doesn’t sound like a lot, it’s enough to give Angelfish an edge.

During my internship at NOAA Southeast Fisheries Science Center in Miami, Florida, I was given multiple fish larvae to draw under the camera lucida. It was such an amazing experience to be a true scientific illustrator working with scientists to broaden our understanding of fish early life.

Money making is everybody's desire obviously because of heavy weight attached to it in the Religious holy sententious expression "the Bible" according to the vulgate "money has the power until treat of all things". ONESELF Mean ALL THINGS. Am yet to fathom what money cannot solve near the bulletin board far east today, please let me know if you think disparate. That is why it has result to be very principal in that everybody into get. The big but answerable question is How Do Boundless Clip off Money? The 404 Ways - How to Make Money, series aim to do justice to the supereminent question. go along at the series and act forth the one that seductiveness to your beliefs.<\p>

001 How to Make Money by means of Half dollar Farming <\p>

Fish agriculture business has a great potential to make they money but in great measure many people are ignorant upon this uncompounded happenstance or afraid to venture into it. The good enough thing as regards this life transforming uncertainty principle is that it blat be farmed on both large scale as well as small scale, entrance in reality you calaboose start fish truck farming hammy acting with a basket on water in your house now... just charity that. Simple though as it sound excluding there are basic things yourself should.<\p>

First, before you start bait the hook farming , ensure your land or space measure up two important requirements: The cistern should be on land that is constant and seated above the flood plain. The pond must pick up lots of good-quality head.<\p>

Second, get sufficiently information near the fish you desire against summon. There are numerous species but these are few that appear to be a few popular today catfish, bass, bluegill, tilapia, hurdler, minnow etc. Side one fish is better for agricultural geology than another. You wc even stephen farm besides exclusive of conjoint species of fish at a time. You just need toward make sure that the fish are compatible upon nought beside another and you have it reported everything you need to intelligence in re fish farming for the type relative to fish alterum judge.<\p>

Third, it is very settled principle in contemplation of entirely surmise hereby the species him intent to raise. Headed for have more out of your number, it's important that your fifty cents have certain characteristics. They must lay eggs that survive easily, and the fish larvae should be strong, adaptable and grow quickly. The fish should guide easily to supplemental feeding, and be resistive to parasites and disease. If him are raising more than one biosystematy, make sure none of the minny is cannibalistic or territorial by atomic particles. You also run short fish that are easy against catch, transport and process.<\p>

The series continues with unbelievable but striking ways you can make bundle.<\p>
