M. martensii

Right bottom is my hand. Top left, the partially visible fish should be a young barbel, they have a pattern unlike the large ones.

Hay does anyone want a fish? his name is Hans William the 17th he is around a year old now and he is almost a foot long. he has a brother named Marly who murdered their other brother bob. Marly is a foot long and he is always hungry. They also have a cousin named Clenora who lives with them rent free. Hans William the 17th is very shy and likes head pats. He requires two baths a week and will nibble your toes. You will also have to get him special cold-water food and keep his home below sixty degrees Fahrenheit. his fins must be brushed every other day and he needs to be fed twice in the morning and once in the evening. When coming to pick him up please don't be worried if you see hundreds of babies. Hans is gay.

Please contact me in the comments if you are interested.

B. macrostoma

Can anyone give an ID confirmation on this (naked?) Goby and tell me some more about where they live life history etc.? Any information appreciated 🙏

This rainbowfish is about a year old now, I’m assuming an egg was stuck to plants I bought last year and it hatched in what was a shrimp tank at the time. It’s finally old enough for me to tell with confidence that it’s a rainbowfish. It’s currently living with a betta, but I’m cycling a 55 gallon because I want it to have an appropriately sized tank. I’m having trouble figuring out if it’s a turquoise or boesmani, or maybe another type of rainbowfish that I’m not familiar with. I’d really like to get it tank mates of the same kind. Thanks for your help!

S. atropurpureus

Wish I'd gotten better photos. There's are through my binoculars. Almost looked like it had bill, or deformed upper lip. Do folks agree or something else?

First time drawing some proper fish with references. I've taken up fishing lately and have had a massive appreciation for these little sunnies <3 I hope to draw some more local freshwater species in the future

Hello.

Spotted this week by the water's edge (in very shallow water) on the French Mediterranean coast.

I don't know much about fish, so any help identifying them would be appreciated.

Well eels are fish, right??
