Rainbowfish In A 4Ft

[meguro]

how many larger rainbowfish are suitable for a 4ft tank if any? i was thinking of getting a small group of m. boesemani and/or m. lacustris to go along with some m. praecox

do they appreciate strong flow?

what type of rainbow fish? there area few!

Melanotaenia boesemani grow to 9cm

Melanotaenia trifasciata grow to 10cm

Melanotaenia parkinsoni grow to 11cm

Bedotia geayi grow to 15cm

i think you could have a few in a 4ft tank. not sure on how many though.maybe 8-10?

Well, that depends on the volume of a 4 foot tank Some 4 foot tanks are 55 gallon, some are 72 gallons (like mine) and some are 75 gallons.

tank is 120x35x45cm, ~180L

6 to 8 would be a good number. Be careful mixing the small species, like praecox, with larger species as the praecox may get picked on.

I'm quite biased towards lacustris though. If kept properly, they show a wide range of colors from green to blue with a brightly colored breeding stripe that ranges from orange to yellow and even white.

How about a school of 7 Celebes, with just a couple of males? They reach ~7cm, just a fraction bigger than the male Neon Dwarf.

Alternatively, how about the smaller Rainbows, like Pseudomugil furcata (Forktail Blue-Eye) and Threadfin? In a large tank, depending on what else you have with the Neon Dwarfs, you could do some nice groups of 10-12 each.

Heck, you could probably combine all the above in a moderately planted, mild current stup and your fish would be in Rainbow heaven (while you adore their great colours)!
