Problems with 2 Orandas
#1
Hi,
I have a 200 litre tank with 3 Orandas in it, they are around 6 months old and have been growing happily with no problems.
Yesterday I cleaned the tank out and installed an Eheim 2217 canister filter along with a 48" air curtain, a couple of new ornaments and a few silk plants (they ate & destroyed all the live ones and were dirtying up the tank previously) - all of which were thoroughly cleaned and scrubbed in hot water prior to entering the tank, obviously with no chemicals.
The fish were moved temporarily to a much smaller tank while I cleaned out the main one which made them a bit miserable understandably but after setting up the new tank they were moved back into the main one and initially seemed fine.
However today 2 of the Orandas are displaying signs of serious distress, neither of them are swimming properly and they both swim upside down, jerking around occasionally and seeking places to hide away which is very unlike them - the 3rd Oranda doesn't seem himself but so far has displayed none of the symptoms.
The tank is now the cleanest it has ever been so I cannot understand what could have brought these issues on? They would appear to have swimbladder problems but both fish also have red vein-like streaks on their tailfins which also concerns me.
I feed them Hikari Oranda Gold food soaked for 15 mins prior to feeding twice a day.
Does anyone have any ideas?
