First, regarding the male betta’s aggression: Male bettas are fiercely territorial, rigorously defending their space in the wild. This aggression is mostly directed at other males: upon spotting a rival, they chase intensely, flare their fins in intimidation, and sometimes engage in fights that can prove fatal. This behavior is an evolutionary adaptation for securing resources like food and habitar, as well as competing for access to females. In captivity, this trait can become problematic, leading them to attack not only other males but even their own reflection in a mirror. Males are also turn aggressive toward females, especially outside of breeding seasons or interterritorial disputes, where they might chase, bite, or try to drive her away. It’s naturally advised to avoid keeping males and females in the same tank exceptional at breeding, as reports show females suffering injuries or death due to male predation. This aggressiveness is heavily influence…

Quilt was a king crowntail who fell in love with a human. He made a deal with the Devil (literally) to become human so he could realize his love, an obvious parallel to The Little Mermaid. However, there's a catch. Since he's shown regularly submerging himself in a bathtub and switching between his human form and fish form (), it can be inferred the transformation's not a complete one. As danhasretired's said in their reply to this comment, bettas can surface in order to breathe oxygen, but that doesn't mean they can survive on land. This drawback could be an allusion to that fact and considered his version of the mermaid's curse. In keeping with the constant breathing imagery used throughout the lyrics, love - to Quilt - is air: something he can't stand to live without, but, should he choose to subsist himself entirely off it, will inevitably lead to his end.

) could be interpreted as a mating between a male and female betta, with the Devil's long, extravagant nails standing in for a male king crowntail's fins, juxtaposed with Quilt's plain, human hands (female bettas have less prominent fins). Not a literal mating in their case, but a union which seemingly leaves the female at a disadvantage.

Now, onto a throughline I'm personally still turning around in my head. Quilt is repeatedly associated with female signifiers. They have an androgynous design, the song uses あたし as their first person pronoun, has them talk about themself "birthing" love, and they're shown looking up at a bubble nest/eggs () whereas male bettas usually guard them (Did their beloved, like the prince, elope with someone else and have children? Or maybe they're looking at the bubble nest/eggs as if puzzling on why their love has yet to bear fruit?). Quilt's hand in parallel with the Devil's (

At some point, pressured in some way to act more aggressively (not unlike how the mermaid is pressured by the prospect of dying of a broken heart after the prince marries someone else), Quilt stopped reverting to his fish form altogether (), signifying that all sense of balance has been lost. The appearance of the dagger, another reference to The Little Mermaid, could mark a similar turning point in the story. Either he choose to die alone or kill his beloved for his own gain. In the end, knowingly walking toward his doom, Quilt turned back into a fish after having killed and cannibalized his beloved in the bathtub so he could literally drown in their blood ("I want to stay submerged / Fill me with love").

the eight months that Biz & Zera have been on hiatus, whether for the production of “Bettaration” or some other project.. have undeniably been worth every second. If I could listen to this song again or experience it live in some way shape or form, I absolutely would. there’s something indescribable that makes their songs so captivating, each release snatches you into this twisted perception of “love”. everything is so uncomfortably seductive, and the raspy, breathy vocals are the cherry on top. whoever this new girl is she’s incredibly endearing. the way she contorts her facial expressions utterly disturbing and intriguing. I think she’s some sort of cannibal too the corrupted ones are the best. I’ve listened to this nearly 20 times now. this song and “Schadenfreude” are going to be favorites for a loooong time. I need to figure out how to burn CDs so I can have it on standby whenever I don’t have my phone. 💉

- Quilt being disabled might play into some broader theme of being disadvantaged. Or maybe it's just an easy way to signify the figure at wasn't him.- If anybody speaks Japanese I'd like to know what the part that points to his fish form on his character sheet says. Machine translation wasn't much help.

@sleepi at it shows a long finned betta fish and male betta fishes typically have the longer fins than the females do, and there were some little stuff shown in the video that male betta fish only do. the bubbles might be one of them cus apparently the male bettas can blow bubble nests and stuff
