I have recently set up my first tropical aquarium a biube.

I have had five Harlequin Rasboras for a couple of months who seem to be doing well. On Saturday I added three Cardinal Tetras. Unfortunatley one died after about 48 hours. Of the two that are left one seems to be struggling. It seems to spend alot of time on its own and is not eating. Is there anything i can do to encourage it to eat? I have been feeding the fish flake food.

Also should it die (fingers crossed it will not) will the other Cardinal be ok in the tank with the Harlequins or should i get some more asap?

One of my Rasboras seems pretty aggressive towards the rest of the fish in the tank. It is always chasing them and seems like it is trying to nip them. Is this normal?

Thanks.
 
I'm sorry to say it but some cardnials and neons are farm raised in farms that arent of the greatest of quality. They can be exposed to desieses like ebola and malaria, along with a bunch of other viruses that cause disentary and diarreah. Secondly, these two types of tetras are extreamly susseptable to shock. It could have been the short trip home that would have caused all the shock to kill some weaker specimens.

cardinals are schoolers, and your remaining fish would certainly appreciate some pals, however, if the fish are quickly croaking I certainly wouldn't be adding additional future casualties as quickly as I could... you mentioned its a new aquarium, how new? check your water parameters.
