Betta fish must haves
Here’s why:
5 Gallon Minimum: bettas need room to move, and bowls do not let them do that (plus have filters and what not). It is cruel to cram them in anything less than 5 gallons (unless they are really struggling to swim, then in some instances that is okay). In general any animal fish or not needs room to move around a lot.
Lid: they need a lid, cat or not. Bettas are notorious jumpers and they can and will jump out of your tank, so it is good to find a lid……because you don’t want to find them on the floor….
Thermometer+Heater: bettas are tropical fish, therefore they like warmer water. Most of the thermometers you find in stores will have a “safe zone” spot on the thermometer where the temperature needs to be
Sponge filter or one with a low flow: bettas (especially long finned ones) struggle swimming in stronger currents. If you have a filter that is too strong then your betta may sit in a spot where there isn’t any current and not swim around as much.
Natural gravel or sand: most times gravel that is colored unnaturally can leak toxins into the water due to the coloring, plus (in my opinion) natural looks wayyy better.
Real or silk plants: bettas fins are very fragile and plastic plants tend to tear their fins. While live plants are usually great for your tank and a good way to go…..they can be really expensive, so silk plants will get the job done and not tear your bettas fins.
Food: any high protein flakes or pellets are good, blood worms and brine shrimp (etc.) are also great for your betta. Any food is good as long as it doesn’t have any plant fillers, bettas are carnivorous!
Tank cycling: remember to let your tank cycle first!!! The pH, nitrates, nitrites, and ammonia should all be at the range or exact number before you introduce your fish, if not it could kill them! Only under certain circumstances is it okay to put a fish (in general) in an un-cycled tank. (Circumstance being if they are in a bowl and slowly dying)
Taking care of betta fish goes beyond just the basics mentioned in the original post. One important aspect to consider is water quality management. Bettas prefer slightly acidic to neutral pH levels, ideally between 6.5 and 7.5, which provides a comfortable and stable habitat. Frequent partial water changes, approximately 10-25% weekly, help maintain optimal water parameters and control ammonia, nitrite, and nitrate levels. Ammonia and nitrite should ideally be at 0 ppm, as even small amounts are toxic, while nitrates should be kept below 20-40 ppm. When setting up the tank, it's also beneficial to include hiding spots such as caves, driftwood, or dense plant clusters. Bettas are territorial and somewhat shy fish, and these hideouts reduce stress and allow them to feel secure. Using live plants like Ludwigia repens or Anubias species can further improve water quality by absorbing excess nitrates and oxygenating the water. However, silk plants can be a budget-friendly alternative that avoids fin damage, as plastic plants may have sharp edges. In terms of filtration, a sponge filter is usually best as it provides gentle water flow, which bettas prefer. Strong currents from other filter types can exhaust bettas due to their long fins and aggressive swimming styles. Also, a reliable heater is required to maintain water at a stable 76-82°F temperature, mimicking tropical conditions, keeping the betta active and healthy. Feeding your betta a varied diet rich in protein is essential since they are carnivorous. While high-protein pellets or flakes work great, supplementing their diet with live or frozen bloodworms, brine shrimp, or daphnia mimics natural food and enhances their coloration and vitality. Be mindful not to overfeed, as bettas have small stomachs; feeding twice a day with small portions is optimal. Lastly, the oxygen level in the tank should be carefully monitored. Though bettas can breathe atmospheric air using their labyrinth organ, good aeration helps keep the water healthy. Avoid overcrowding the tank and selecting compatible tank mates such as snails or shrimp if you plan a community setup. Male bettas are aggressive and usually best kept alone unless the tank is large, with proper visual barriers. In summary, a well-cycled tank with clean, warm water, gentle filtration, secure lid, and natural habitat elements are critical to betta health and happiness. By including these supplemental care tips, aquarists can significantly improve their betta’s lifespan and quality of life.










thank you for promoting accurate husbandry/care for bettas. I love them so so much. our female betta is named Unicorn, and lives in a planted 20 gallon ʕ ꈍᴥꈍʔ
