In one sentence, describe what the following article is about: If you aren't able to prompt slimes to spawn in a swamp biome, you may have more luck underground. Slimes spawn in caves located in "slime chunks", which are 16 x 16 x 16 block areas. You have a one in ten chance of coming across a slime chunk. When below layer 40, slimes can spawn in any light situation; adding torches will both make mining easier and prevent other hostile mobs from appearing. This constitutes a chunk. Slimes won't start spawning immediately while you're here, but you may be able to force them to do so by adding platforms. These platforms should be stacked on top of each other with three blocks of vertical space between each. Having these platforms increases the possible spawn area for slimes. As with the swamp biome, slimes won't spawn if you're 24 blocks (or closer) away from the spawn area. If you don't see any slimes within a standard night and day cycle, you'll need to find a new cave.
Summary: Search for caves below the 40th layer. Add torches to the cave. Clear out a 16 by 16 by 16 room. Create four one-block high platforms. Retreat at least 24 blocks away from the spawn area. Wait for slimes to spawn.

Problem: Article: This is the optimal temperature for keeping the baby guppies comfortable and hungry so they'll eat enough food for healthy growth. If your tank temperature isn’t within this range, you can install a heater in your tank. Choose a heater that can handle the capacity of your tank.  Cold water will make your fish too sluggish, while very warm water can harm the fish. To check the precise temperature of your water, use a thermometer that sticks to the side of your tank. You can find a tank heater at a local pet store or online. Follow the directions on your filter model to place it in the tank.  Baby guppies don’t have a strong immune system, so they’re vulnerable to disease. A filter can keep your water clean enough to protect the fry, though you still need to change the water often.

Wipe any algae or grime from the sides of the tank. Finally, refill it with fresh, clean water that’s been treated for chlorine. Wait until the tank thermometer reaches the optimal temperature for your guppies before you return them to the tank.  If you can’t change the water every week, replace at least 1/4 of the water each week with fresh, clean water. Chlorine can harm your fish, but you can neutralize it. Purchase chlorine treatment tablets or liquid from your local pet store or online. If you don't have this, let the water sit out for 24 hours before you use it to replace the water in your fish tank. Baby guppies that grow up in dim lighting may develop deformities, especially in their spine. A regular tank light installed at the top of your tank is all you need to give your fish light. Turn the light on in the morning, then turn it off in the evening. Don’t leave the light on longer than 14 hours a day, as the baby guppies need to be able to sleep.
