Help!!! Rasbora Hets are dying
I have a 75g freshwater aquarium. I have had 18 Rasbora Hets for about a month now. However three have died in the past three days. I observed one sinking to the bottom of the tank and then wildly swimming around before dying. I checked my water and here are the conditions:
Nitrates - 20 ppm
Nitrites - 0 ppm
Hardness - approx. 300 ppm
Chlorine 0 ppm
Alkalinity - approx. 90 ppm
PH - 8
Temp. - 78F
*Note: My water is very hard with a relatively high PH. However all of the fish were born locally in similar water conditions.
Tankmates - 7 Small Koi Angelfish, 6 Japonica Shrimp, 1 Bushy Nosed Plecco, 1 Flower Shrimp. (No one has been aggressive that I have observed).
I have two Marineland HOB filters.
Did you see any physical signs of illness like ich? When you say one was wildly swimming about, was it rubbing against objects (parasites) ?
No physical signs of illness. No bulging eyes, no white spots. He wasn't rubbing against anything. He just started swimming violently in circles and then just stopped. Someone recommended I soak frozen food in garlic extract. I guess it's supposed to help flush out the digestive system including parasites and bacteria.
That's strange, never heard of the garlic thing either. Sorry but I don't know exactly how to help. :-(
That's okay. It is definitely a mystery. I just hope I can find the cause before I lose them all.
:-( Yes, good luck.
