What type of care do they take?
Snails are pretty easy to take care of. Some feed off detritus that falls to the substrate when you feed the fish. Others are herbivorous and eat "bad" algae within the tank. You normally don't have to do anything specific to keep snails. Just need to make sure you have the proper pH, temp, and SG
that you would keep fish at. This is basically all most snails need. You should make sure that you actually have algae for the herbivores to eat before buying them. If you don't, then they may starve to death. This is only a problem with newly setup tanks. There isn't an established tank out there that doesn't have enough algae to support a normal sized snail population.
What types are best for clearing brown algae problems?
If you are talking about diatoms and algae, there are a few snails that can take care of your problem. These include:
- Astrae Conhead
If you want some snails that will eat detritus then here are some more choices:
- Nassarius Snail
- Cerith Snail
