Bettas are actually pretty smart fish. They respond really well to training with food. Same for goldfish and most cichlids.

Weedy scorpionfish (Rhinopias frondosa)

Rhinopias frondosa is a benthic marine fish which belongs to the family Scorpaenidae or also known as the Scorpionfishes family.The weedy scorpionfish has a highly compressed body, can reach a maximum
length of 23 cm, and can vary considerably in color as well as
appendages depending on its environment. Specimens found in rocky, algae rich waters are covered in weed-like appendages, whereas specimens found in deeper soft-bottomed waters with soft corals and sponges have fewer appendages. Color can range vastly from dark red and purple to yellow and lavender.The weedy scorpionfish lives in the Indian Ocean and Western Pacific Ocean, from Japan to Australia and from South Africa to the Caroline Islands. They are found in depths ranging from 13 to 90 meters.Like most Scorpaenidae, weedy scorpionfish are mostly nocturnal ambush hunters, using their camouflage to prey on unsuspecting fish and invertebrates. They rarely swim, but rather move along the bottom propelling themselves with their fins.

my 20g as of right now! really liking how it turned out

Nice! Love cherry barbs. There’s a few nice males in there.

For those unaware, those are cherry barbs. Much less aggressive than most species of barb, they do well in communities. Most of their chasing is for show, they don’t nip fins or bully. They have the best colors when they have plenty of cover, like here. Those especially bright red ones are males, and that really bright one to the left is probably the dominant male.

Cuttlefish can change color to fade into the background. It can do it amazingly fast.

These are flamboyant cuttlefish, and that looks like potentially a threat display rather than an attempt to hide.

my favorite thing about fish is when they’re separated by families, genus or continents but just rip each other off

Most of our perception of what Goblin sharks looks like comes from dead specimines where they are all mangled and shrivelled, and are always positioned with their jaws protruding out.

When while alive they only ever extend their jaw for feeding, and arnt half as creepy looking

they do look like goblins

this also disregards the fact that they can still propel their jaws forward like an aquatic xenomorph from hell

So can many other fish, I’m just not judging them for their beautiful smile.

personal favourite

why is the ocean like this

what a question

that’s just what ocean is like

if it skulks on a reef, and has two sets of teeth,

that’s a Moray.
