will glowlight tetras school with noens or cardinals

Lucy

I've read that if fish are about the same size and shape they'll school together.

im thinking of going all tetra, get ride of the guppies & danios.If i go all tetra how can i fit in my tank..??

TFA101

for tetras, you can follow the one inch per gallon rule

spider_pig

I'm not sure if they will school, i know they're compatible but i doubt they'll form a shoal all the time. If you go all tetras you can have a lot of them and it will make a stunning display

6 cory cat, 5 cardinal 5 neon 5 glowlight in a 20 long tank?

spider_pig

Sounds great, i would get some more cardinals though, maybe another 3

TropicalGrimmish

i know i love my cardinals, but i want equal number of each.

TFA101

you'l have to rule out one of the tetra species as the tank is a little overstocked. You'll have to have good filtration and keep up with the water changes

spider_pig

then i would take out the neons and have 7 glowlights and 7 cardinals

TropicalGrimmish

than how many tetras can i fit in my tank i really like to know many i can squeeze in my 20 long tank so im not overstocked,remember the corys, " have a 10gal topfin & 20 gal topfin power filters running with bio 3 filters.

Nick Goody

As long as they're small tetra's (neon's, glowlights,etc), you could easily keep 20-25 in a 20gal.

spider_pig

i would say 15-20

With regular water changes

TropicalGrimmish

with the corys??

spider_pig

yeah, why not?

Nick Goody

Sorry, didn't realise you had Corys too. 6 Corys and 15 tetra's would be fine with regular maintence.

TropicalGrimmish

i mean ya the corys are fine, what i ment was number of fish.. 6 neons 6 glowlight 6 cardinals 6 corys

Nick Goody

That'll be fine. Tetra's have very small bio-loads,and Corys are basically vacumn cleaners! With regular water changes 6 of each will be fine in a 20gal
