  • Cultivating live food for your fish friends is a great idea! Research, trial, and error are going to be really important in the process, so it’s better to do it in a separate tank to keep your fish safe. We don’t have the ability to bring an entire complex ecosystem into our homes and put it in a glass box; the best we can do is mimic one as best as possible. This means that an experimental tank won’t have as many of the same “redundancies” nature does when nutrient, light, or oxygen/dissolved gases get out of balance, and population crashes can happen a lot more easily. (Even if it’s just the food creatures that die off, the decaying matter can cause problems like ammonia burns for your fish.) Rather than trying to establish a sustainable colony of food animals in your fish tank, starting a tank with food animals and slowly adding fish to it will give you a much clearer picture of how large a population they can sustain.

    Some tips to help you build as robust a system as you can:

    • Use a 10 gallon (about 40 liters) or larger tank. Greater water volume means increased stability because the water dilutes concentrations of things like ammonia and gives you a nice buffer for environmental changes; a 5 gallon (about 20 liters) tank will have much narrower safety margins and will make it harder to figure out where the problems lie.
    • Add a lot of plants, both in number and variety, to improve oxygenation and reduce carbon dioxide in the water. They’ll also provide food and grazing surfaces for a lot of smaller food animals.
    • Use a canister filter or AquaClear-style hang-on-back (HOB) filter that gives you a lot more filter medium for housing the microbes that process nitrogenous wastes like ammonia, nitrite, and nitrate than a single, fiber-covered plastic cartridge. Don’t run charcoal or activated carbon in it unless you’re finishing up a round of disease treatment–it’ll pull out a lot of the stuff the tank’s plants and animals can use. Canisters and HOB filters will also give you better gas exchange than an undergravel or sponge filter will.
    • Tank barriers are easy to make out of plastic mesh used for crafts like needlepoint. I think the holes would be big enough for most food animals to swim through, but not allow fish in their area, but I’m not sure.

    This sounds like a really cool project. If you decide to do it, I hope you’ll post updates!













  • If the reason you don’t want to speak to an adult for guidance is because there aren’t any you find trustworthy or who know how to communicate effectively with you, I think the best way to learn from your mistakes is to look for the patterns around them. Then, shift your perspective from being the person who made the mistake to being someone on the receiving end of it–walk a mile in someone else’s shoes to understand them better and all that. For me, I found getting to know myself a really important part of this: I had to know what I was like when I felt my best and worst to recognize the things that went wrong before I made a mistake. It took me until adulthood just to recognize that I have a slow-to-warm personality and tend to be inflexible, which means that any unexpected changes really fuck my shit up and can lead to me making mistakes because I feel like I’m scrambling to adapt. Give me an extra minute or three to live with it and I’m fine; don’t give me the extra time, and I’ll probably be nasty towards you even if you don’t deserve it. Recognizing those patterns in my own behavior lets me say, “Hold on, I need a few before I can do what you want” instead of, “Are you fucking kidding me? You’re doing this again?” (which, it turns out, upsets the people who are so ready to demand I do something flawlessly and on their schedule instead of mine, lol).

    Looking for the underlying causes of mistakes is like tracking down clues to solve a mystery. Maybe you missed a throw because your hands were sweaty and the ball was slippery, or maybe you miss a throw because your mind was busy trying to work on a different problem while you were throwing a ball. Maybe an unexpected gust of wind blew the ball in a different direction than you were expecting it to go; mistakes aren’t always because of things that we can control, so it’s important to be fair and kind to yourself when you’re looking for these patterns behind them and recognizing when something isn’t your mistake.

    It’s way too easy to get wrapped up in the idea that making mistakes makes you a failure or a bad person. Nah, they just mean that you’re doing something you’re not used to doing perfectly. Nobody just hops on a bicycle and rides off into the sunset on their first try. It’s a skill that takes practice. There are tons of skills like that that most people don’t think of as needing practice before you get good at them: making friends, being a good friend, creating emotional boundaries, saying no, saying yes, asking for help, washing dishes, fixing a leaky pipe, emotional regulation, apologizing, forgiving, driving… it’s a long list, but you get the idea. Being bad at a skill is a temporary thing, and making mistakes is how you figure out how to improve.





  • No, large water changes will not typically crash an established cycle. The vast majority of the bacteria that break down nitrogenous wastes live attached to surfaces: filter media, hardscape, substrate, and plants. Filter media are designed with surface area in mind: the hang-on-back (HOB) filters using the plastic cartridge covered with fiber floss has lots of slots to allow water to pass through and over the fibers, which are frizzy and are easily colonized. Canister filters hold stacked baskets of media like porous, ceramic rings that are designed to maximize surface area and house a ton more helpful organisms than even the fiber-covered plastic cartridge.

    When starting a new tank, it’s a good idea to throw some of your existing, healthy tank’s filter media (or plants or hardscape) in to jump start the community of microorganisms that keep your aquatic buds safe. You can use a friend’s, but only if you’d trust them to care for your fish at least as well as you do, as harmful organisms can also attach to surfaces and be carried along.
