Temperture For These Galaxy`s (pic)

[beechey]

all the stats are fine, none of my discus have died or hatchet fish just these keep dying so think the temp may be a bit high for them tank is at 30DEG

were 10 now a lonely 1

They're from the same family and genus as danio's even though they were originally considered rasbora's... 30 degrees is probably a little high for your hatchetfish and it really seems high for the galaxies, I would put the one alive in it's own filtered tank at around 23-25 degrees. That's going to make them much happier. 30 is ideal for your discus and probably alright for the hatchets but way too warm for the galaxies

I could also see the tiny galaxies being a nice snack for the discus. With the warm temperatures is takes out a lot of the much needed O2 for the galaxies which would cause them to swim towards the surface more to get more oxygen... This is just an asumption but the reccomended temperature for these guys are much lower than 30

I've have 8 of these little guys since Jan 2006 without a death (not bragging, just wanted to highlight that they aren't delicate because I'm no expert). I should really do ph readings but I don't... I have them in a 5 gallon tank without a heater in my office. The temp is always the same in the tank, because I don't have windows in my office and no drafts; 25 degrees celcius. I do weekly water changes and siphon up any gunk that accumulates at the bottom of the tank. i have a few real plants in the tank which they like. They are active and social with each other and seem happy.

So... I can only conclude that your temp might be high but more than likely your discus are snacking on them. Have their little bodies dissapeared entirely?

As mentioned twice before, you sure your discus aren't eating them . Seems like a silly mix, but I have no experience with discus personally...

When you say your stats are fine, what are the actual stats?

Discus are typically kept in acidic water, and you have already said you have them at 30 degrees celcius.

With regards to the Celestial Pearl Danio's preferred water stats:

The species lives in cool, alkaline water of around 24C or less.

Source here.

They aren't in the same genus as danios though....danios aren't all in one genus . Danio is a genus in the sub-family Danioninae, and the term danio is frequently given to other members of this sub family, including the 'Celestial Pearl Danio' (Celestichthys margaritatus) formally known as the Galaxy/Fireworks Rasobra (I thought Fireworks Rasbora was the best name ).

These little chaps are so small, I don't think i'd keep them with anything other than fry!

A small suck and they'd disappear into any open mouths.

Are they just dying or disappearing?

Oh. and the temp seems high.

Of course the temperature is too high, they are caught from a mountain stream at high altitude so the water is going to be cool and highly oxygenated. Putting them in a discus tank with 30c temperatures and low o2 levels is as good as putting them in bleach, practically guaranteed to kill them.

cheers people lol last one is dead , they were in with my baby discus no more galaxys for me,

 

[thegnu]

for anyone keeping the Galaxy/Fireworks Rasobra try feeding them last thing at night with the tank light off and a room light on for they are quite a nocturnal fish and quite unique (their large eye gives a clue to this. for the size of the fish it's MASSIVE) could be why they remained undetected for so long!

 

[PaulEbs]

Tell me if I'm wrong, but aren't these fish getting to be endangered now?

 

[three-fingers]

Yeah, numbers are apparently diminishing fast and habitats are being wrecked by people with nets.
Only for them to be shipped thousands of miles and eaten by discus/die of heat exhaustion. IMO the only people who should be buying these fish right now are people seriously intending to breed them.

Nice one!

Note :

Discus + Galaxy's = Rasbora Sushi

 

[beechey]

night_market the galaxys were in my baby discus tank, and died because the heat was way wrong as i kept them at 30 deg,

Weren't they only discovered in November of 2006?

 

[Matty P]

Yeh 30 is way too high for them

August 2006 according to what i've read on the net. I keep mine in a tank without any other fish in it, hoping they will breed. They look as if they might from their behaviour. They really don't seem like difficult fish to me, I'm sure people have had successes breeding them by now. I should look that up.
