Fish
Happy fish start with the tank: clean water, steady gear, peaceful tankmates, and food that fits the species.
Flakes, pellets, frozen foods, wafers, sinking foods, and light feeding.
Plants, hides, caves, driftwood, swim space, and safe decor.
Cycling, testing, water changes, algae, quarantine, and easy routines.
Tanks, filters, heaters, lights, substrate, test kits, nets, and conditioners.
Stress, water trouble, fin damage, temperature swings, and stocking mistakes.
