How Many Fish Can I Fit Into A 50 Gallon/250 Litre Tank?

[JamesGunn]

I plan to upgrade my current 15 Gallon tank to a larger 250 litre tank and I was wondering how many fish I could get in there. For example how many Glass Catfiah could I fit in there? Or what would be the largest fish I could comfortablely keep in shoals? Also which are compatable and can live together?

glass catfish you could keep a decent 14ish shoal depending on tankmates.maybe you could say what fish your intrested in so we can find out if there compatible or not.

 

[JamesGunn]

By tankmates i mean would they be compatable with fish like red rainbows, bosemani rainbows, bettas, corys, platies, mollies etc?

I wouldn't set any stall by that chart; it's far too generic.
 
Just looking at barbs, there are so many different species, of such differing sizes and temperaments, that that chart would be useless.
 
OP; is your water hard or soft, and are there any species of fish you particularly want?

 

[ncguppy830]

well what i meant was that would be the starting point and if they werent sure they would ask.

 

[JamesGunn]

Well I would be looking at getting a shoal of glass cats but are there are fish that could live with them ie a single gourami, betta, and what can silver sharks live with?

 

[ncguppy830]

defintaly not a silver shark! i wouldnt keep em with a betta because the cats are nippers from what i hear, i think the gourami could be fine depending on the type of course.

 

[JamesGunn]

So could large cory cats be kept in a tank such as that with gouramis etc!

 

[ncguppy830]

depends by your definition of large but yes.

Glass catfish aren't in the least bit nippy, IME.
 
They are very peaceful
 
They do prefer soft water though, whereas most rainbowfish like harder waters. I keep mine with cories, green neon tetras and marbled hatchetfish. 

 

[JamesGunn]

So how many marbled hatchetfish could I fit comfortablely in a shoal?
Also how long would my tank have to be up and running ie I know that neons need a tank that has to mature for at least 6 months plus, so are hatchetfish the same or different?

 

[fluttermoth]

Is your water hard or soft though?
 
I don't want to be recommending species that like soft water if you have hard!

well then weve had different expereinces because the glass catfish i had often nipped the longfinned fish id with bthem IE betttas,fancy guppies

 

[fluttermoth]

Oh well, I don't keep bettas or guppies, so I wouldn't have noticed those tendencies!
 
I will say I am surprised though, it's not something I'd imagine them doing!
