Q: If you decide to breed your Corydoras, you of course need to know that you have both males and females. The differences are easy to notice, and you can check them by looking at your fish from above. Females will be a little larger, with a rounder and broader body, while males tend to have slightly larger pectoral fins.  If you intend to breed your Corydoras, you should try to get a ratio of two or three males for each female. If your fish are ready to spawn, you will notice the males chasing the females and mating in the T position. Once they have mated, the female will lay her eggs against the aquarium glass, or among the leaves of the plants in your tank.  In the wild, Corydoras usually spawn during the rainy season, so you can encourage mating by simulating these conditions. If you begin to notice your Corydoras engaging in spawning behavior,  perform a water change with slightly cooler water. Once you notice eggs in the tank, you should separate them from the parents. Corydoras will eat their own and each other’s eggs, so if you want new Corydoras, you should make sure the eggs and parents are in different tanks.  One way to do this is to move the Corydoras to a separate breeding tank when you start to notice them spawning. Once the females lay eggs in the tank, you can move the fish back into their regular tank, and let the eggs hatch in peace. You can also remove eggs to their own hatching and raising tank after they have been laid. Keep the water conditions as similar as possible. If the eggs were laid in the plants, you can simply transfer the plants. If you’d prefer not to remove the whole plant, it is fine to cut off the parts where the eggs are and just move that. If the eggs are on the side of the tank, remove them by rolling your finger over them. Eggs are tough, so you shouldn’t do any damage removing them this way. The eggs should hatch in three to five days. Once that happens, the new hatchlings, called “fry,” will be able to survive on their yolk sac until they start swimming freely. Once that happens, provide some brine shrimp nauplii (a type of larva) or decomposing plant material for them to eat. After about a week, you can start including microworms into their diet.
A: Check the sex of your fish. Watch for your fish to spawn. Separate the eggs from the parents. Feed the new fish.

Q: It's normal for kittens to sleep through most of the day, especially young ones. When they are awake, though, they are full of energy. Let them nap, but provide scratching posts, toys, and things to climb for when they wake up. A bored kitten during the day is a hyper kitten at night.  Keep most of the exciting, interactive toys hidden when you're not actively involved. If you leave a toy out on the floor all day, the cat usually loses interest. Do not leave out toys with string, since these can be dangerous when tangled around the kitten.  Puzzle games are an excellent way to keep the cat entertained. These challenge the cat to open a container to reach a treat inside. Cats are most active around dusk and dawn, not through the entire night. A daily play session in the late evening, roughly an hour before bed, will help sync this schedule to your own.  You can mimic play fighting with a toy on a string, play fetch with a ping pong ball, or play chase with a laser pointer. Rotate toys to keep it exciting and to provide a mix of stalking, chasing, pouncing, and toying with the "prey."  Wake the kitten up if necessary. You shouldn’t have to keep this up for too long before your pet learns that evenings are for play and nights are for sleep. It's best to end playtime before the kitten gets bored. First, spend five minutes slowing down the pace of play to calm the kitten down. Find a clear way to signal that playtime is over, for example by letting the kitten catch an extra enticing toy. If your kitten is getting hyperactive near the end of playtime, distract its attention to a less exciting toy. Make this a high-protein meal that completes the kitten's food needs for the day. Cats in the wild hunt, then eat, then sleep, so this playtime and food routine mimics this pattern. If your cat wakes you up in the morning meowing for food, delay the evening meal until just before you get in bed, instead of before you get ready. This way the cat has less time to wait between meals. Start your normal bedtime routine with the kitten watching. This teaches your kitten which activities signal bedtime for both of you, and helps establish a routine. Turn out the lights and bring the kitten to its bed. Hopefully the kitten will be tuckered out at this point. If not, calm it down with cuddles or by playing relaxing "music for cats" from online playlists. Repeat this routine every day, and the kitten should learn to adapt. Cats are natural observers and enjoy being up high to observe household activities. A high perch or "cat condo" is a great sleeping spot, as long as your kitten is old enough to climb it safely.
A: Allow rest and stimulation during the day. Wear out the kitten with evening playtime. Bring playtime to an end. Give the kitten a bedtime meal. Head to bed. Calm the kitten in a comfortable sleeping area.

Q: Search online or in companion books for runes that are specific to the Shadowhunters universe. Since runes are the source of Shadowhunters’ powers, decide which powers you would personally like to have. Examples include Angelic Power, Clarity, Courage in Combat, and Mental Excellence. Since Shadowhunters often try to keep their runes hidden from sight, pick an area that would normally be covered by clothing. Even if you plan on hitting the streets without long sleeves, keep your character authentic and avoid areas like the back of your hand, neck, and face.  If possible, ask a friend to draw the runes on you, since this will allow you to cover more area with more runes than you could manage on your own. If you don't have anyone to assist you, stick to easy-to-reach places like your chest, stomach, arms, as well as the tops of your thighs. Depending on your flexibility, you could also possibly include more of your legs. For runes with more intricate designs, or even simple ones if you would rather not attempt drawing them freehanded, print each design from your computer. Use scissors to crop the paper until you have a rough square around the image. Then trace around the edges of the design, both inside and out, with a utility blade or exacto knife to create a cutout for stenciling. Tape the outside edges of the cutout to your skin and stencil yourself first with waterproof eyeliner, which will help prevent your rune from running should you start to sweat or otherwise get wet.  When you create your cutout, be sure to save any blank paper that has been cut from the inside of the design (such as the squarish piece in the center of the Angelic Power rune) so you can tape these pieces separately to your skin in order to complete the stencil. Do not use kohl pencils, since this material will rub off onto your clothes. If you don't have a printer, practice drawing your rune on paper a few times before you attempt to draw the rune directly onto your skin. Once you feel confident, tattoo yourself freehanded with black eyeshadow, since this is easy to wipe off your skin in case you slip up. Once you are happy with the result, trace over the eyeshadow with waterproof eyeliner for a longer lasting temporary tattoo that will keep its shape despite sweating. However, before applying any new products that you haven’t used before, apply a little bit to a small patch of skin to test whether or not you have any adverse reactions. If you are drawing your runes on your own body, be sure to practice drawing them according to your view of the area where it will be place. For example, if it will be on your chest, practice drawing the design upside-down since this matches your view of your own chest.
A:
Pick a design. Choose its placement. Use cutouts. Draw your tattoos freehanded.
