Can I put an African Dwarf Frog with my female betta in a 3-gallon?

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.

You will need to use a solid or opaque divider to obstruct their view of one another. If they can see each other, it can stress them out. As the male matures, he will want to breed with the female and she will spend time swimming as far from the divider as possible to move away from him.

A male Betta can be kept in a 10 gallon tank with 5-6 neon tetras. You will need to monitor for any aggression initially as well as for any fin nipping. Male Bettas are easy to distinguish from females by their brighter colors and larger fins.

Female betta sororities are not "bad". They can be tricky to set up though. A 75 gallon tank is more than adequate for 15-20. Try to get them as close to age and size as possible and introduce them into the tank as a group. Provide PLENTY of cover (plants, hiding spots). Initially, there will be some squabbles and nipping as they establish their own heirarchy. Remove any that are overly aggressive. A betta tank may be too warm for Corys. Bettas do best between 78 F and 80 F whereas corys like water a bit cooler, 65 F to 75 F. A spotted leaf fish would not be recommended. It would likely eat the smaller bettas once it is grown.

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!

The small size will limit the species of fish as well as the number. White Cloud Minnows or Guppies would do fine in a small tank. You could keep no more than 2 or 3 fish total. If you are looking for company for your Betta, the same species can be kept. Other options include Otocinclus (Otos), Corys, Platys or Harlequin Rasboras. Again, no more than one or two in addition to the Betta. Water changes for any tank are simple. Change no more than 30% total volume at a time. Use a water conditioner to remove harmful chemicals and make sure the water is temperature matched to prevent stress or shock. Rinse the filter in tank water, not tap water, to preserve beneficial bacteria. Vacuum the substrate every couple of weeks.

Hi there! The general rule of thumb is 1 gallon for each inch of fish, so I think that you may need a bigger tank. If the bettas are 2 inches each, they each require 2 gallons of water, making the minimum tank size 14 gallons. Since male bettas can be territorial and aggressive, I highly recommend a larger than normal tank with lots of hiding places for 7 fish (at least 20-25 gallons). You should also watch them very carefully for fighting, and have a backup plan in case any of them need to be separated. Good luck!
