needle fish will certainly not work well with neon's, they will murder the neon's
Yes,Neon tetras and catfish live together well.
You could have a school of neon tetras (approx 6), or 1 fancy goldfish
Neon Tetras do very well in soft and slightly acidic water. If there are a couple of Neon Tetras left, it may be best to quarantine them in a separate tank.
That is not a very large aquarium, so a shoal of neon tetras would work well
they eat tropical flake foods as well as blood worms and krill
By its general size and appearance. Most Tetras are not long lived fish and depending upon species, live for 3 to 5 years. I would advise buyers to always buy from a reputable breeder if possible. If you can't find a good breeder then use a reputable pet store and after researching the species, buy fish from healthy looking, active schools of tetras that are not quite full size.
It is 9 gallons and has 4 neon tetras 4 black neon tetras and 4 glowlight tetra s. As well as 3 algae eaters and 1 hong Kong plec- is that too many?
That is fine. You might consider getting some corydoras catfish.
In my 20 gallon aqaurium I have three neon tetras and a clown loach which have been togethor for a few months now. So far they have not bothered each other so it would work out if it is a small clown loach and you have other fish in the aquarium as well.
It certainly won't do well and probably will die. Neon tetras evolved in the tropical, acid waters of the Amazons lakes and tributaries with around a pH5.5 to pH6.
Betta fish can flourish in a community tank, however because they are at times aggressive fish (males especially) correct pairing is crucial. Bettas usually get along well with neon or cardinal tetras, platies, mollies, guppies. Stay away from tiger barbs and cichlids, they tend to pick on or even kill bettas.
Well, it depends on their size. From what I've heard, you can put one inch of fish into a tank per gallon, so: 5 one inch fishes of 1 five inch fish etc. It doesn't matter about the fish unless some are aggressive and the others are not.
