I have a 20 gallon tank high standard sized tank. It is already cycled and has 2 hang on back filters totaling up to like 250 gph.
Ammonia:0
Nitrite:0
Nitrate:5-10
Ph:idk yet

So far i have about 5-7 adult guppies and like 5 or more babies or frys aka. Its okay if the guppy overbreeds because i will feed all leftover guppies and females to my oscar.

How many more small fishes can my tank hold if i do 25 percent water changes a week.

I was thinking 7 more green neon tetras and 7 cardinal neon tetra?? Is this good and a bristlenose pleco also.

Are tiger barbs okay?

i wouldn't go with tiger barbs if you want to breed the guppys. tiger barbs are aggressive in small numbers and are fin nippers

I agree with Marcus, Tiger Barbs are not really suitable fish to mix with guppies, I suspect they will probably eat any young that you get a may even kill the guppies.

i would tell you to get apistogramas ..cockatoo dwarf cichlids ...and keyhole cichlids ..they are tiny .and colours are incredible !!!!!!!!! breed readily and have personalities of cichlids !!!! PERFECT

YOU MUST HAVE THESE FISH ....I WOULDNT BE WITHOUT MY DWARF,S ..

Crap BGH, Now I need to set up another tank! Thanks

awwwwww honnestly nicki thay are amazing lil cichlids ....they only get to about 1 1/2" fully grown .i love em and you will too ....theres about 10 different apistograma species and they are all amazing !!!!!!!!!!!!! go 4 it ..






they keep well with bolivian and blue rams too ...just for a bit extra colour and form in the tank



they are realy small and a 20 galon tank with decent filter and a weekly 30% waterchange will easily house 15-20 fish

NEED THEM, WANT THEM, LOVE THEM!!!!!

wow! those are gorgeous fish! darn-it too! I want them!!!

not sure if they would be suitable with guppies - I'd recommend checking the water requirements. are they south american - so maybe they're ok?
neons or cardinal tetras should be fine with guppies

I want to know more about these little cichlids! maybe start a separate thread?? sorry to hyjack the guppy question:)

they have no special requirements ...exactly the same as any sa/ca cichlids ...and he said he would feed the guppies to the bigger fish anyways ....thats why i recomended the apistos ..

thanks big-game! I think you may have started something here you may get enough of us excited enough to start new tanks just for them!

are they aggressive at all? How about breeding? can you mix the different ones together?
