15 Gallon Suggestion ?

[singlecutguitar]

I have est 15 gallon tank, is it sufficient enough to keep 20 zebra danios, 3 cory and a rainbow shark ?

Unfortunately, no. What're the dimensions of the tank? Corydoras are schooling, so should be kept in groups of 6-8+. Danios are very active fish, and need a lot of swimming space. 
 
What about a school of corydoras, a small school of harlequin rasboras and a betta? You'd be slightly over stocked but with plants and adequate filtration would be ok.

In a 15 gallon I personally wouldn't keep anything but one of the Pygmy Corydoras species which are C. hastatus, C. habrosus and C. pygmaeus and you could have a decent shoal(up to about 15) of them in that size tank if it's a 15 gallon long tank. Along with those you could have Galaxy Rasboras(a big shoal of them) and maybe a male betta or a pair of Dwarf Cichlids
 
What are the full dimensions of the tank?

I disagree with this. Personally I think I was pushing it with a pair of rams in a 20 gallon. I agree about the dwarf corydoras, but wouldn't say to have 15 of them in a 15 gallon in addition to other fish! I think 8 would be edging it with a shoal 8 of rasboras and a betta.

Correction, it is starfire red glofish, I think they're also zebra danios ?
 
the tank ist 600X295X360mm
 
I have them in seperate tank, I want to join them in single community tank. I won't add betta because I prefer high current tank with powerhead.

 

[SamB]

I would (and this is an estimate) say that you need 55 gallons or so to keep those fish happily in the same tank.. that would give them enough room. 
 
For this tank, you could maybe do dwarf puffers? They would be interesting. Unfortunately there is no way you can keep over 20 fish in this tank.

 

[Paradise3]

OK maybe 15 was a high estimate, I was thinking of a different tank when recommending the number of corys by accident. I think 8 would be good I think a pair of dwarf cichlids would be OK. I have a pair or Gold Rams in my 19 gallon and although the recommended is 20 gallons I think that's more to do with aggression when breeding than size as they are very small compared to other cichlids.
 
Or you could go for Apistogramma agassizii which are recommended a pair for a 24x12x12(LxWxH) which is only 12 gallons  
 
Your tank is 60x29.5x36 cm's? That's only 14 imperial gallons and 64litres
 
So yes, you could have;
 
2x Apistogramma agassizii(Male and Female)
8x Corydoras pygmaeus/hastatus/habrosus
8x Danio margaritatus
 
This would all look nice in a small planted set-up and would be nice and active but not overstocked as they are small fish that all have their own territories.

Hm. I still think the danios need more space to swim (very active fish - not so much a matter of size as it is of swimming space). I would recommend something a little more calm / peaceful to go with the apistogrammas

They aren't danio's, they are Galaxy Rasboras which are less than an inch each and are actually quite calm for a Rasbora species

 
Edit: Their other name is Celestial Pearl Danio but they aren't like Zebra Danio's in activity or anything. I've seen a tank of them. They shoal but they don't dart around

 
Another edit: A quote from Seriously Fish

The OP's tank is 60x29.5x36 cm
 

 
Despite its small size we wouldn’t keep a group of these in anything with base dimensions measuring less than 45 ∗ 30 cm due to the sometimes combative behaviour of dominant males (see ‘Behaviour and Compatibility).

 

[SamB]

Whoops, I had been thinking of a completely different fish!

Haha, yeah they are quite calm for a danio/rasbora species They do shoal but not like zebra danio's, they shoal closely and slowly rather than with slight distance and rapidly

Unfortunately there's not much fish selection in the market here. Every seller usually sell same kind of fish at the same time. The red glofish danios have become trend in the today's market since it already enter indonesian market. I consider to buy some, but my biggest tank is about 15 gallon. How many zebra danio can I keep in this tank ?
 
Generally the breeder more often breed local fish species like tiger barb. clown loach, arowana, or shark than species that originally from outside Indonesia. They become species that always avalaible here. Some species outside Indonesia like Oscar also available since breeder also breed them, but not african cichlid (except yellow lab).

Are danios and rasboras different species ?

 

[Paradise3]

Danio's and Rasbora's are technically different species but they get confused so much.
 
How about buying online? You can get all of what I mentioned online
