My rainbowfish tank today.
I actually was expecting this one to fall into complete disrepair. Specifically because these guys need some care spent to ensure stable oxygen and cooler temperatures than what my house's ambient temperature usually allows for during the hot season days. On top of that, their food needs to be finely crushed for the threadfins, because their mouths are so small. Our housekeeper is not an aquarium person, and so she only had my instructions to work with [on top of maintaining everything else in the house] and honestly...she did the best I could have asked for.
There was definately a tempurature issue (or something) at some point, and I lost a few guys to that. We're down to 6 threadfins [from 7] and 3 blue eyes [from 6], and 3 ottos [from 4]. But everyone who's still here is looking and eating well. Though some of my threadfins are looking very lean, everyone here is gonna be just fine.
Something totally out of my housekeeper's hands is the state of my anubias plants...Before I left, an anubias in the bottom right corner had a strage issue where it dropped all of its verdant, healthy green leaves as the rhizomes melted away. I figured it was just a problem with that one plant, but upon coming home last night, I saw that I had lost a few more to this same problem. And this is how I learn that "anubias rot" is a thing. Apparently it's not known if it's a fungus or bacteria, but it's not responsive to chemical treatments and there's not really a way to cure it. I suspect that these plants, like all plants, have a healthy biome of microflora/fauna that livea on their root structures, and I wonder if I fucked that up for them when I treated the tank with kanaplex and metroplex a few months back--and what ever causes the rot was allowed to slowly over take the rhizomes as a result...I don't know.
Regardless, I'm gonna have to replace those plants...maybe with something that doesn't have rhizomes for now haha.
Lastly, the water's looking a bit milky, suggesting a bacterial bloom--so I was initially worried that my cycle had crashed. But--
the parametres actually look beautiful, the tank's robust! So prolly an autotrophic bloom from the plant and fish dieoffs. Regardless, house keeper definately stayed on top of the water changes, but u really just need one lost fish corpse to kick a bloom off.
Anyways, I'll keep a close eye on this over the week and if things look good and stable and none of the remaining fish decline, I'll replenish the stock. I'm just so happy the ecosystem itself survived and left me with plenty to work with. I was fully prepared to have to scrap this tank and start over with it, but no! It's alive and well, just needs a little tlc.
