So story time: this tank has been in a state of semi-neglect for a while bc of depression/a couple fish deaths/all sorts of stuff. My school of fish has been pared down to my two cardinal tetras in my 20 gallon planted. Except for snails, this tank has ONLY housed those two cardinal tetras for about a month since their last two buddies died. They’ve been under standard but very minimal care (because again, your boy’s been depressed). I figured these two tetras would die eventually and have been kind of waiting on that so I could revamp the tank once I’m feeling better.
Buuuuut my tetras decided they had other plans!!! because today I discovered they have a baby!!! I only saw one so far, and I assume the rest of the egg clutch didn’t hatch into babies or the siblings died off, but check it out! I’m a fish dad again! And to egg-laying fish, which…yeah idk how I did that either! 😆🐠🐟

[IDs: The current WIP of my new merman OC, which is based on a longfin morph neon tetra. One sketch is in black and white and the other is in my layer colors. End ID]
2025 is the year that Mara finally breaks down and adds mer to the maraverse
*slaps the top of his head* this sad boy first. i need a name for him

New aquarium's third day!
60L dirted tank. Floating plants helped clear up the water. I'd love some anubias on the wood.

This capture was exposed for the brighter background and the fish had come out darker. The fish was then separately brightened up in post.

One of the delightful and iconic tropical fish is the cardinal tetra, Paracheirodon axelrodi, a fish many of us consider to be a more difficult version of the similar neon tetra, P. innesi. Indeed experiments have shown P. axelrodi is sensitive to products of the nitrogen cycle, but perhaps surprisingly tolerant to temperature and pH, given its reputation for being a difficult and delicate characin. Nowadays the cardinal tetra is captive bred more often than was the case in the past, though the vast majority of imports remain wild caught. Former childhood aquarists will likely remember learning how to spot the difference between the cardinal tetra and its neon relative, from the Amazon basin. In fact there is also a second neon tetra species, the green P. simulans, which makes P. axelrodi the third, with its being closer to the blue than to the green neon species
P. axelrodi is a petite, pretty, and colorful fish with a bold demeanor and a schooling nature. At their largest, fish of this species grow only to 2.5 centimeters or 1 inch in length. Our aquariums offer them a more stable habitat than in the wild, so they grow larger and live longer in our artificial environments. It's natural range is tropical and South American, being distributed in the upper Orinoco region of Colombia and Venezuela, and the upper Negro of Brazil. In fact there are a small number of color morphs naturally occurring among this popular species, and the populations of the Negro are considered to form a distinct geographical race from those of the Orinoco.
Natural habitats of P. axelrodi are small and slowly moving streams, with notably low carbonate hardness and conductivity, and also a low pH value. Sometimes this can be as low as 3.5, but fortunately for us, 5.5 to 6.5 will do them nicely in the aquarium. In the wild, P. axelrodi have the same gregarious nature they do in our aquariums, and furthermore they often school with other small tetra species. Not surprisingly this charming species makes a great community fish, when it is cohabited alongside other small and peaceful species, and must always be maintained in conspecific groups.
The temperatures that P. axelrodi experience in their natural habitats are similar to that of our tropical tanks, because in the wild this species associates with shady, overhung habitats. Without the presence of such shade as is provided by trees above, the water temperature would probably be a few degrees higher, which would be something this species does tolerate, although not as high as 35 degrees. In our aquariums, this species flourishes as 23 to 26 degrees centigrade, or a bit higher as in a slightly warmer, discus style aquarium.
Like many other tropical aquarium fishes, P. axelrodi is extensively insectivorous, thetefore feeding this species is not in the least problematic. Wild P. axelrodi are essentially feeding on the mesofauna that is associated with underwater plants, roots, and leaf litter. They can be characterized as insectivores, because most of their diet is prey such as insect eggs and larvae, cladocerans, and copepods, whereas their ingestion of algal marerial is infrequent.
