- I recommend switching his food to either New Life Spectrum Betta pellets or Omega One Betta Buffet.
Foods that contain a lot of grains/fillers can cause constipation, bloating and/or buoyancy issues. Look at the label of your current pellets, and look for words like "gluten, corn, soybean, potato, wheat, rice, etc." If you see words like this, consider switching to a high-protein pellets such as New Life Spectrum or Omega One. These two brands are well-tolerated by Bettas, and cause fewer digestive issues.
- Yes, Epsom salt can be used in a tank that has live plants. In fact, Epsom salt is often used as fertilizer! (However, don't use Aquarium salt in a planted tank.)
White feces can be caused by several things, including parasites and stress. I recommend that you start a new thread about your fish. This will allow people to look at him, and read about his symptoms. Be sure to include the information on the sticky located here
- Hm, no. It can be OK to use Epsom salt for a longer period of time. It simply depends on what condition is being treated. I think you may be thinking of Aquarium salt. Aquarium salt has a high sodium content. This places stress on the kidneys, and can lead to fluid retention or bloating, etc. I do agree with your comment about fasting a bloated fish for several days prior to medicating it. Often, fasting alone can help resolve the bloating/fluid retention. If it doesn't, the next step is often either Epsom salt (magnesium sulfate heptahydrate), or frozen/live daphnia. Both Epsom salt and frozen/live daphnia have laxative effects, which can help 'clean out' a constipated fish. (Don't feed freeze-dried foods though, as these can cause additional constipation issues.)
