I want Angel Alvarado to answer this question. What fish can i put in a 3 gallon tank besides shrimp. If I have to get neon tetras please tell me how to change their water. Thanks
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.

Hey! Just got a beta fish and he is swimming fine... but after I fed him, he seemed to “hyperventilate”! But then again, he’s swimming fine. Is this okay? He’ll also swim really fast at some points. Is he just nervous?
Monitor for redness, white spots or fuzzy growths on him. The swimming fast may be "flashing", which a fish with an infection will do to "scratch an itch". Maintain pristine water quality via filtration and partial water changes. Use only aged or conditioned water that is temperature matched to prevent stress or shock when performing water changes. Bettas do best between 78 F and 80 F. Monitor water chemistry to confirm 0 ppm ammonia and nitrites with nitrates at 320 ppm or less. If you don't have a home test kit, most pet stores will test water for free or for a small fee.

I have a 20 gallon tank. I'm thinking of buying +5 fish. Which fish could I buy and what would I need for the fish and tank?
A fish tank will need a filter, a light/hood and a heater. Make sure the filter is rated for at least twice the tank volume. The heater should be adjustable since water temperature will depend on the species of fish. Good "starter" fish include Tetras, Mollies, Danios or Tetras. A new tank should be set up and left running empty for several weeks before adding fish. A pinch of flake food can be sprinkled in daily. This "cycling" will allow a population of beneficial bacteria to colonize the tank and filter. These bacteria will break down wastes (ammonia, nitrites and nitrates) which are toxic to fish.

I just bought my betta fish yesterday from a local shop ever since i bought it does not move much and keeps sitting at the bottom of the tank and has not eaten the fish food the owner gave me it keeps flapping its gill rapidly its my first time ownin
These are quite concerning signs. The tank where you place Ale is absolutely inadequate and will soon cause serious consequences. Water Quality and Temperature: Make sure your tank has a filter and especially a heater, room temperature is too cool. They are better off at about 78-82 degrees. If kept too cool, they get lethargic and refuse to eat. Bottled spring or drinking water seems to work out well. Never use distilled water. If kept in dirty and unfiltered water they are prone to fin and tail rot and other bacterial infections. Tank Size and Habitat: Some reccommend a five gallon tank with light filter and heater is perfect They do not like strong water current and should be provided a place near the surface to 'take a load off'.' Petco sells the betta hammocks. Also keep your Betta happy by providing artificial or live floating plants for them to swim around. Feeding Your Betta a Well-Balanced Diet: Betta pellets or high quality flake food. They can be fed every other day with

My male Betta fish isn’t moving
Check the water temperature. Bettas do best between 78F and 80F. Low temps can affect activity in fish. You may need a small submersible heater to maintain water temperature. Next, check water chemistry. You can do this with a home test kit or by submitting a water sample for testing. Most pet stores will do this for free or for a small fee. Confirm an absence (0ppm) of ammonia and nitrites with a nitrate level of 40ppm or less. Partial water changes may be indicated to stabilize chemistry and maintain water quality. Use only aged or conditioned water that is temperature matched to prevent stress or shock.
