What type of fish can I keep with my adult male betta fish, he is in a 3 gallon tank.
Most of the compatible fish are schooling fish that do best in groups of 4-8. This would include Neon Tetras, Ember Tetras, Harlequin Rasboras or White Cloud Minnows. That many fish may be too much for a 3 gallon tank. Other non-fish option include Ghost Shrimp, Zebra Snails or African Dwarf Frogs.

Hello! I have a 3-gallon tank at home that I previously used for my betta fish. Now I am looking to purchase another fish (possibly a few fish) but I am not quite sure what my options are. What types of fish would you suggest for a 3-gallon tank a
Hi Tori, I have found that fancy guppies are pretty, fun, and small fish that would do well in a small tank. Mollies would be another good choice. A 3 gallon could probably support 3 or 4 of them well. Beta fish don't seem to care much about snails in My experience. Have fun!

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.

Where can I get a brislenose pleco? Their are none for sale on the Petco website.
I would recommend to call the local pet stores (including Petco) and ask if they ever carry that species. Sometimes the fish can be out of stock. Some of the smaller fish stores can have a good variety of fish available. Best of luck!

Hi, I have a Betta fish and it is very low on energy level these days and it is losing his color.
Bettas are tropical fish. They need warm water. They do best between 78F and 80F. Clean water is key in treating any infection. Check water chemistry using a home test kit or by submitting a water sample for testing. Aim for 0 ppm ammonia and nitrites with a 40ppm or less nitrate level. Perform partial water changes to stabilize chemistry and maintain water quality. Use only aged or conditioned water that is temperature matched to prevent stress or shock. A bit of aquarium salt (NOT table or Epsom salt) can be used as a general tonic to reduce stress, treat minor infection and aid in any recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup of tank water and gently pour it into the tank. Treat for 10-14 days then reassess fin condition. More water changes can be done afterwards to reduce salinity.
