Hi I'm looking to buy a male Betta in the next couple weeks and keep him in a 5 gallon tank by himself. I had a Betta several years ago and remember the hassle of changing the water, so this time around I was looking to buy a filter. What would be
A small tank with one Betta will require minimal upkeep. Most small HOB (hang on back) filters will be sufficient. Tetra, Fluval and Aqueon make a wide range of acceptable filters. The tank should have a cover or hood as well as a light and a heater. Bettas do best between 78 F and 80 F. Feed 1-3 pellets once or twice daily. Change the filter as per manufacturer instructions. Rinse filter media with tank water, not tap water, to preserve beneficial bacterial populations. A partial water change, no more than 20-20% of total tank volume, may be necessary every 2 weeks to maintain water quality and stable chemistry. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Water conditioner brands include: AmQuel Plus, NovAqua, Prime, StressZyme and StressCoat. You don't need all of them. Follow the directions on the bottle. Allow the tank to cycle before adding a fish. This will allow beneficial bacterial populations to colonize the filter and substrate

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!

I keep my Betta Fish in a 6 gallon tank. Is it to small? Do I need a bigger tank? Thanks!
A 6 gallon tank is fine for one Betta. You don't want to go any smaller than 5 gallons unless you want to perform frequent maintenance. Be sure to provide adequate filtration, low current and proper temperature (78F to 80F).

Which fish and plants suitable in planted tank (75 litre ) ?....And which substrate use are.....And how to medication apply for Discus and tetra fish in planted tank without harm to plants and biological filter ?
Java Moss, Java Fern, Anubias and Amazon Swords are among the easiest live plants to care for and cultivate in an aquarium. You can use aquarium soil or aquarium sand depending on the species of plant(s) chosen. When medicating fish, it is best to remove them to a hospital or quarantine tank. This will spare live plants as well as beneficial bacterial populations, especially if an antibiotic is used. Medicated food is also an option.

I got a baby betta fish and was wondering how do I care for it : as in habitat , water changes , feeding and heating
Mushu is very cute! Betta care is very easy. Ideally, a 5 gallon tank should be used to house your Betta. A smaller tank can be used, but the maintenance (water changes) will be much more frequent. A filter is always recommended otherwise water changes will be required every few days to maintain water quality. With a filter, 20% water changes can be done weekly or every two weeks. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Choices for conditioners include AmQuel Plus, NovAqua, StressCoat, Prime or StressZyme. A small submersible heater is necessary since Bettas are tropical fish. They do best in slow moving water between 78F and 80F. You can feed a pelleted diet such as Hikari Micro Pellets until he grows bigger. Baby brine shrimp, daphnia, bloodworms and blackworms can also be fed. Feed one or twice daily. He should only need 2-3 pellets at each feeding. The conditioners and food can be found in the aquarium section of the local P
