Hey I want you to look at some Pikeblennies (the genus Chaenopsis). At first they just look like neat long boys:
But then! Look at those big ol’ branchiostegal rays! (Those are the bony rays under the jaw).
And they scream!
So small! So much rage!
Anyway I think they look like little duck-snake-dragon hybrids and I love them very much.
That last two are ‘yelling’ at mirrors. That’s a territorial display meant to impress. They are Very Determined to be impressive.
These photos are great. In addition, a territorial fish that sees a mirror image, flares at the image, and stops seeing the image, like if you take the mirror away, thinks it’s won. It’s probably satisfying as heck for them.
Finally got my dream tank running. My little Ryukin water puppies seem to enjoy schooling around which is really cute to see. They like to follow the tiny little babies around for some reason? The smallest fish I have is the gang leader.
If you’re wondering why
there is a bucket in there? That’s because while I do have
my dream tank, my dream filtration system is still on the to-buy list.
If you ever find yourself short a filter something like my bucket idea might help you. It’s a cheapo ebay pond pump in the bottom of a hardware store plastic bucket, the biological media out of the old canister filter poured around it and some cotton filter material on top of the ceramics and a couple river pebbles to hold it down.
Didn’t actually cost me a cent because I had the stuff lying around already. You could use something similar. All you need is water flow and something to direct it over your media.
Oh, nice! I bet your goldies love it, all that sand to play in, and they’re gonna look amazing once they get big.
Give them a couple ping-pong balls, goldies like to play with them.
Acanthodes
“A fossil discovered near Hamilton, Kansas in the Upper Carboniferous Hamilton Formation, and published in 2014 as Acanthodes bridgei was so well-preserved that traces of its eye tissue were sufficient to establish that Acanthodes had both rod and cone photoreceptor cells, and thus profited from color vision
The candiru fish is a species of parasitic freshwater catfish. It normally attacks the gills of large fish.
Supposedly, it can swim up a stream of urine and into a person’s urethra if they pee in a river that the fish lives in. This is not physically possible, both because you can’t swim up a falling stream of liquid and because the fish is too large to fit into the urethra. Babies are not too large, but have no incentive to swim up someone’s urethra.
Supposedly this is because they’re attracted to the scent of urine. They are not, they hunt by sight. To be fair, this was only discovered recently.
Supposedly the people who live in candiru habitat wear coverings to keep the fish out of their junk. Those coverings are for piranha defense.
Supposedly there are people who’ve had to have their penis amputated after a fish swam up it. Again, piranha, in this case responsible for the amputation.
There have been a few cases of an apparently confused candiru fish ending up in someone’s vagina when they were swimming naked.
So, basically, don’t swim naked in the Amazon. If you have a vagina, the chance of getting a fish up it is very small, but you still don’t want to deal with things like piranha. Also, minnows nibbling on your junk probably doesn’t feel good.
