general betta fish care / common myths
there's a lot of myths fueled by pet store employees floating around about bettas, so the more this kind of information is spread, the better. as always i encourage everyone whose looking into fishkeeping does THOROUGH research long before getting the fish and do NOT rely on pet store employees to give u accurate information.
"bettas aren't good swimmers or active so they don't need big tanks and are perfectly happy in a little bowl or a flower vase"
"they're super hardy and resilient so don't worry about tank cycling"
"bettas like dirty water so don't worry about cleaning either'
"live and frozen fish food arent good for everyday feeding"
"bettas can't be kept with other fish ever bc they are extremely aggressive and will kill anything with a pulse"
(we're gonna debunk all of these (: )
the first thing that should be in your possession long before adding the fish is the tank. a lot of fishkeepers think 2.5gallons is the minimum, but personally i think 5 gallons is the minimum. 10 gallons works best. to reference, 2.5 is the minimum by AMERICAN standards, which are outdated, so many people choose to go by germany's standards instead because it's proven to be a lot more successful & up-to-date.
a 5 gallon tank is the minimum that i recommend, but 2.5 gallons are ok.
10 gallon tanks work best. the bigger your tank, the more likely your betta will grow to maximum size & beauty, the less likely chance of stunting growth.
also, 10 gallon tanks are much easier to maintain and establish a cycle, and you can even start an albeit small community tank with them. (with tank mates compatible with your betta & small enough to not outgrow a 10gal. but community tanks are a topic for another day)
properly cycled tanks reduce disease risk & encourage longevity in your betta's lifespan (i will make another post about the nitrogen cycle bc that's a lot)
a filter! nothing with a strong flow, though. bettas are not very good swimmers! (tip: when cleaning your tank, never rinse the filter media! it kills beneficial bacteria & basically starts your cycle all over)
a heater - bettas thrive best in 78-82 degrees F.
water conditioner. i recommend seachem prime - it's the BEST out there and contains helpful nutrients that get rid of bad bacteria & ammonia.
bottled bacteria, if necessary. helps kickstart the cycle of your tank.
pH and ammonia testing kits
gravel syphon for cleaning & maintenance
a net to fish out uneaten food
gravel/substrate. (tip: measure how much u need by laying the bags out across the tank box. it should fit evenly across it long-ways)
decorations!! don't get plastic plants, they can harm ur betta's fins. if ur getting fake deco, try to find silk ones or very soft ones. bettas like to be divas so make that shit pretty as hell & give them lots of places to hide. marimo moss balls are good for helping tank filtration & super easy to care for if ur interested in live plants!
INTRODUCING YOUR BETTA TO YOUR TANK
acclimation and tank cycling are still CRITICAL to a betta's life and happiness. it's true that they are resilient fish that are easy to take care of, but like any fish, they have vital comfort needs & are still going to get diseases if you don't care for your water quality!
1. when you first bring home your betta, do your final check on those water parameters. do an ammonia test in the fish's cup water to see just how much of a battle the pet store caretakers made for you. almost 100% of the time the ammonia levels will be in the danger zone.
2. this is why acclimation is so very critical. start small and take your time. empty out a bit of the cup water, add a bit of your tank water. empty out a bit more of the cup water, add a bit more of your tank water - with about 3-5 minutes in between takes. keep doing this until you have replaced most if not all of the filthy pet store cup water. (WARNING: WATCH FOR SIGNS OF SHOCK WHILE YOU ARE DOING THIS. CLAMPED FINS, THE "SHAKES", FLOATING ON ITS SIDE, ETC ARE ALL SIGNS THAT YOU NEED TO ABSOLUTELY SLOW DOWN & LEAVE THE FISH ALONE FOR A COUPLE HOURS.)
3. now float your betta. you can put them in a bag if it's easier, otherwise you can just hold the cup in the tank. let the temperature adjust & let your lil guy/gal get their first glimpses of their new home. do this for a minimum of 10 minutes
4. gently tip the cup into the water & let the beast free! continue watching for signs of shock and keep a close eye on them & your water parameters for the first couple days.
frozen or live brine shrimp, bloodworms, & mosquito larvae are betta favorites. when handling frozen food always rinse it out before putting it in the tank - most of the time the food is frozen in water that becomes really gross and murky. dried bloodworms also work very well. for flakes and pellets, i always recommend Omega One betta buffet flakes/pellets because their food is all natural and contains no additives/"meals" (tip: don't buy any food that lists something followed by the word "meal" in the ingredients; it's basically heavily processed food).
do NOT overfeed. honestly underfeeding is better than overfeeding. you should feed your betta once a day with as much food as they can eat in about 2 minutes. have them fast one day a week to clear their digestive system. their stomachs are smaller than their eyeballs, so really, DON'T overfeed. it can cause a lot of incurable issues AND mess with your water quality
remove any uneaten food, or if you have bottomfeeders in your tank let them have at it
bettas will literally eat six #12s, 7 medium fries and a large shake if you let them. dont let those big black eyes trick you lmao
if you have a very young betta (5-10 weeks old) feed them twice a day instead of just once. brine shrimp eggs are especially tasty for fry but if your lil guy is big enough, they can eat regular frozen brine shrimp. meaty products filled with protein help them grow the best. (bettas are full grown at 11 weeks, here is a size chart to determine your adolescent betta's age)
note that even if it worked out for everyone and you've gotten 800 recommendations, things can STILL go wrong when keeping bettas with other fish. ALWAYS be prepared for an emergency move. also note that sometimes things can work perfectly fine for the first couple months and then go to shit within a couple seconds, especially when pairing young bettas with other fish. young bettas develop, you know, hormones at some point and start getting supa territorial.
also, please make sure you have the proper tank size to keep any of these fish together. i've included their adult sizes & my recommended tank size if you were to keep nothing but the betta and this species in the tank. this WILL vary.
clown plecos - 4" full grown - algae eaters - 20 gallon tank size min.
pygmy corydoras - 1" full grown - schooling fish (you will need 6 or more of these) - 15 gallon tank size min.
ember tetras - 1" full grown - schooling fish (again, 6+) - 15 gallon tank size min.
rasboras - 1" full grown - schooling fish (again, 6+) - 15 gallon tank size min.
mystery snails - 2" full grown - plant-safe snail, doesn't reproduce asexually - 5 gallon tank min.
ghost shrimp - 1.5" full grown - social shrimp (3-4 of these, any more can lead to breeding) - 10 gallon tank min.
feeder guppies - 1" full grown - normal, can live in schools but not necessary - 10 gallon tank min (larger recommended for schools)
corydoras - 2.5" full grown est. - algae eaters - 15 gallon tank min.
and there are many, many more but these are what has, to me, at least, been the least problematic tank mates for bettas. all of these fish have something about them that would deter an aggressive betta's attention, such as the armor plating on clown plecos & dull colors of the pygmy corydoras and feeder guppies.
okay, so i think this covers all the basics! if you guys have any questions, please ask! and if you have anything to add, please do! thanks for reading & happy fishkeeping xxx
