Rio Tapajós Damming: Belo Monte’s Sequel?
The next posterchild in Brazil’s damning of the Amazon is the São Luiz do Tapajós Dam
Belo Monte: Protests mount against “Monster Dam” on Brazil’s Rio Xingu
Biologists and human rights observers are calling it an epic disaster in the making, a massive river-damming complex in the heart of the Amazon basin that threatens tens of thousands of native rainforest dwellers and the fish populations that sustain them and enrich the aquarium world.
¡Viva Baja! New Monterey Bay Aquarium Exhibit Looks South
Just when you think the visual delights cannot get any more dazzling, you round the final corner and all the color drops away to reveal a perfectly simple display: a fat, round tank where hundreds of brilliant silver Lookdowns (Selene vomer) swim circles all day, their long flat noses bright against the tank’s calming, blue-lit interior.
Battlelines Drawn as Brazil Pushes for Mega Dam on the Rio Tapajós
After the loss of an epic battle over the Belo Monte project on the Xingu River (the huge dam started operations in early 2016), the Tapajos is expected to become the primary focal point of forces opposed to damming the wild rivers of Amazonia.
XINGU Rising
Río Xingu is ground zero for what has been called the worst environmental disaster in a generation—the highly controversial, widely reviled Belo Monte Dam. This infrastructure project, which has been in development since 1975, has been reported even in mainstream international news outlets, mainly due to the fact that its impacts will include catastrophic environmental and social costs for the entire Xingu River basin.

I'm a DEMACRAT. I'm getting a pair of (AFRICAN WOLF CICHLIDS) the scientific name of it is africansis k9 they are the real wild wolfnature fish unrelated to the central American wolf cichlid they are faaar worst in aggression they are KILLERS PERIOD theres not many cichlids that stand in their way they are not recommend to keep by many Americans cause of the killer nature only 8% of people have them.John C Gern says:

Sumer, Thank you for your well written and comprehensive article. I enjoyed it very much and it is not too long at all. I have kept bettas for about 60 years. My first pair spawned in a one gallon glass pickle jar, only one male survived to maturity. You wrote that your water is less than 10 TDS. I assume you start with RO/DI water. What and how much do you add to get to 10 TDS? In the egg exchange portion of the video, the male's right operculum appears to be slightly malformed (too short). Is there a malformation or just a camera angle? I have seen 2 males with a malformed operculum. Too many inbred fish? I've been giving the 2-3 day swallowing problem some thought. This 2-3 day or sometimes 5-7 day period from spawning to swallowing is consistently seen by many people trying to raise Macs. It can't be that everyone startles their holding males on day 2 or day 5 and that makes them swallow the eggs. It seems to me that this behavior may be an instinctive response to non viable eggs. Somehow the male fish gets a signal (probably chemical) from the "rotting eggs" and that triggers the swallowing. The male swallows the eggs rather than spits them in order to conserve energy. Fish sperm motility (swimming speed and duration) is strongly affected by the make up of the water, particularly the osmolarity. So TDS, or a very narrow range, may be THE factor that determines whether the sperm fertilizes the eggs and whether he swallows. Currently, I have 16 adult Macs. I keep the pH at 5.5-5.8, the TDS less than 30 ppm. In one 10 gallon tank there are 2 males and 1 female. The males chased each other at first. Now they watch each other, but there has been no damage to either. The female previously spawned with each of the 2 males in a 50+ gallon grow-out tank. I put them together hoping the female would spawn with each male in an alternating pattern. But today she spawned with both males, one after the other. it took about 7 hours. Both males are holding now. The female is resting. What do you feed fry? I feed live BBS, and very finely ground Betta Bug Bites. Then switch to frozen Daphnia, fruit flies and white worms.

Joseph, I too have heard that it can be done but have never done it myself or seen anyone else do it. Since the males are known to eat the whole brood, I would suspect that it'd be very hard to strip the male of the fry.The male might just swallow the whole brood when the keeper would approach to catch the male. Do you keep Betta macrostoma? Have you heard or seen someone practice "stripping" with Betta macrostoma male?
