Harlequin Raspboras not eating...

I started my tank this past Friday (it is wed) and my betta can't be better...he's 3 and it's like he's got a new life...loving the tank. I got 4 raspbora because the clerk said no more than 4 to start to condition the tank. At first they were spritely and darting all over. Ate like piranhas. 2 days later they hardly move from the corner of the tank and just stare out ...actually one goes to the other side and stares out in the opposite direction. Yesterday they ate and even stole food meant for the betta(poor betta didn't know whether to chase them away from his meal or try to eat it.)

They aren't eating now. they don't look sick but my tank has the lowest hardness (0) and high ph 8.2...the other levels of ammonia nitrate and nitrite are non existent as one would expect from a new tank. They were perfect for 2 days straight and then started this strange trancelike behavior last night. I read that one needs more than 4 in a school, but I didn't want to overload the tank at first. Do they not eat when not schooling? Do I need more? I didn't want to get too many since we plan on getting a few bottom feeders and another 1-2 middle tank swimmers. I want a minimum of 10 fish for the 16 gallon tank.
thanks,Anni [/URL]

I'd get two more, they really need to be in groups of 6. As for them not eating, it could be shock or stress. annizoe, I'm not sure if they are good cycle fish, but I know they have low bioloads.

I just lost one to a betta...actually he's still alive and in a net. I'm surprised since the betta is very passive and ignored them for 2 days. I knew this "could" happen and am glad I was there to see it before he got more. Sadly the raspbora no longer has pectoral fins. I need to euthanize him but have no idea how! Old school was to flush, which they say is not good...but to cut it's head off? I cant do that!

Bettas really are best kept alone, if you have another tank I'd remove the rasboras.
Flushing is not only a slow painful death it's quite possibly illegal, it is over here.
This thread may help you on methods of euthanasia

betta ate raspbora's pectoral fins!!! Others look "sick"

I am shocked to find that my very passive betta has anger issues. He just ripped off the pectoral fins from one of my raspboras! It is still alive and in a net and I am beside myself as to what to do! The betta has been moved to his old home, and the three remaining raspbora's look lost and are at the net. I need to euthanize this poor suffering creature but I can't cut off it's head as suggested (plus he's so small!) Old school was to flush but I've never thought about doing this with a live fish.
Actually my kids called me over...as I sit here typing...they notice that the others are extremely lethargic and one looks to be dying (swimming erratically.) They did so well for 2 days! I don't know if the betta attacked them or maybe he attacked because they aren't well?

No, he attacked it because he is a Siamese Fighting Fish....the active word being "fighting".

This is a good case study for why you don't keep Betta's in community tanks


As for your parameters, do you have many plants? If not that would indicate you haven't cycled your tank, and you have some serious work ahead of you.

I'm so sorry things didn't work out.
Hope you other fish are feeling better soon.

So you put a "male" betta in the tank? "He just ripped off the pectoral fins from one of my raspboras!" "He"

I wouldn't be too quick to euthanize. Fins will grow back and he/she may make a full recovery.

Edit: I merged your two threads.

What's the tank temp? Double check.
At the beginning of winter, I had my heater go out, light still came on but water was freezing, fish started acting weird, and didn't realize it till I touched the water.

PS- the betta will NOT be returning to the tank. He is responsible for the one death but the others? Perhaps he had nipped at them or perhaps they were shocked somehow. Perhaps the betta sensed that they were sickly? I would like an experienced point of view. Yes my mistake was trusting my betta (who is afraid of his own shadow.) That I get...but what would cause the last raspbora to act fine for another 2 hours and then suddenly...start dying? I feel horrible. Petco will take them back and they said that they recommend just a few "trial" mollies/guppies since the betta wont be there.

Well, some bettas are peaceful for a long time, then snap, it kills all the rest of the fish.

the kit did not come with a thermometer and forgot to buy one! It is an automatic set heater. Water is warm (that is not a very good answer.) but when I return the dead fish I am going to buy a better one with an adjustable thermostat...kinda annoyed with the kit I thought all heaters had an adjusting dial...jokes on me.

that will be top on my list of priorities tomorrow! BTW I was backwards about cycling. I was told that since my betta was in the tank and thriving that it was cycled...can't be...even though I used old fishbowl water there was no way the bacteria could have been established. Going to buy a few cycling fish tomorrow with my dead fish refund...any recommendations? (soft water high ph) Mollies? Guppies?
