Can I keep platies, mollies, plecos, and neon tetras in a 20-gallon tank?
In general these fish can all be housed together safely. The one thing to keep in mind is the amount of space needed per fish to maintain a safe and healthy environment. Each 1in of fish needs 1 gallon of water. So in a 20 gallon tan you can have 20 inches of fish. The Pleco is the only one I have concerns with as some varieties can grow quite large. Check with your local pet shop as to what needs best suit this type of fish or what type of fish suit your tank best.

Do rounded or half-moon fish tanks harm my fish or distort vision?
It should be okay to use these tanks as long as they have proper filtration, lighting...etc. Round bowls typically don't have filtration, lighting...etc and that's what will adversely affect the water quality. I hope this helps.

Why are my angelfish and red tail shark sick in their new tank?
Check the water chemistry and temperature. Use a home test kit or submit a water sample to test fro elevated ammonia or nitrite levels. Most pet stores will do this for free or for a small fee. Partial water changes can be done, if indicated, to stabilize chemistry and improve or maintain water quality. Ideally, you want 0 ppm ammonia and nitrites with nitrates at 20 ppm or less in a non-planted tank or 40 ppm or less in a planted tank. Use only aged or conditioned water that is temperature matched to prevent stress or shock. You'll need to keep the temp at the upper limits for Red Tails in order to keep the Angelfish comfortable. That would be in the 78F to 80 F range. Both have similar pH requirements, 6.8 to 7.5. You can fast the Angel for 2-3 days then feed bits of cooked, shelled green peas. This will usually resolve constipation and bloating. Pristine water quality may resolve the patch on your shark. Recommending a medication without more information or a clear image would be risky to the stability of the tank's nitrogen cycle. You can use plain aquarium salt (NOT table or Epsom salt) as a general tonic. It will reduce stress, improve gill function, may treat minor infection and aid in recovery. Dissolve 1 tablespoon per 5 gallons of water in a cup of tank water and gently pour it into the tank. Treat for 10-14 days then reassess the condition. A note on tank size: Although the two fish may be fine in a 15 gallon tank now, you will likely need a larger tank as they mature. Red Tails can reach 6-7 inches and Angels can reach 6-8 inches. At adult size, a 15 gallon tank will be insufficient and could lead to some aggression from either fish.

What plants can I put in my 24L tank with shrimp, snails, and fish?
Thanks for reaching out about your tank. Long plastic plants that extend from the bottom, all the way to the top can providing hiding spaces to decrease any territoriality or aggression. Live plants might be susceptible to the snails, depending on their type. Good luck.

What's the best tank size and setup for a happy, healthy betta?
A 2.5 gallon tank is fine for a Betta and 2 snails. If you have artificial plants, use ones made of silk instead of plastic which can harm delicate fins. You'll need a heater also. Bettas are tropical fish and do best between 78 F and 80 F.
