Putting betta fry in direct sunlight with 15 cm depth of water - will it aid their growth or will the temperature rise be a problem for them?
Re: is it safe to keep betta fry in sunlight?
Most fish aren't too fond of direct sunlight, especially without any floating plants to provide cover. It's not just the heat, they can get stressed out from birds eyeing them up as a potential snack.
In a pond with floating plants, they're generally okay, but if the water gets too hot, it's game over. So, if you've got a pond outside in the sun, make sure it's got some shade during the hottest part of the day. Adding some aeration to circulate the water and boost oxygen levels is a good idea too. Baby bettas, in particular, need this since they can't breathe air until their labyrinth organ develops around the 3-month mark.
Larger volumes of water are better at holding their temperature, and they don't get those massive temperature swings throughout the day. Shallow containers, on the other hand, can have temperature changes of 10-20 degrees between day and night, which is not ideal for the fish.
In larger bodies of water, the fry can hang out just under the surface where it's warm, and if it gets too hot, they can always dive down to cooler water.
