I have had this small silver arowana ( about 4 inches ) for about 2 months now and he has been doing fine. Today he won't eat ( he tries to eat but spits the food right back out as soon as he takes it in ). Also I noticed a dark patch forming on the top of him behind his fin. It is just behind his eye. I have been doing weekly water changes and am running an eheim professional 2 filter 2026.
The only thing I have changed is I added a charcoal filter to my eheim about 4 days ago. Before that I never had a charcoal filter in at all.
The only other thing I can think of that may have something to do with this is perhaps I am overfeeding him. I give him a big pinch of PACIFIC Plankton twice a day- mabey this is too much. I don't think this is the case because I have been doing this for a month or so and he has been fine with it up until now.
Anyway, this is what I have done: 1) removed the charcoal filter from the eheim 2) did a 30% water change 3) added some AQUASAFE water conditioner that is supposed to provide a slime coating to help heal wounds 4) added quite a lot of CYCLE to the tank.
Is there something else I should do?
Was it the charcoal filter that has had this effect on him?
He is in a 90 gallon tank right now ( I will be getting a bigger tank when he outgrows this one ) and he is looking a little sluggish right now. And as I said before he is not eating and there is a dark patch on him.
One other thing I should mention is that before I added the charcoal insert the water looked a little brownish/yellowish. I think this is because I have a couple of big peices of driftwood in the tank. When I added the charcoal, the water became nice and clear after a few days but I do not know if this had an adverse effect on the arrowana?
I tested the water and here are the results...... AMMONIA - 0
NITRITE - 0.1
PH - 8.0
NITRATE - 0
TEMPERATURE - 80.8 degrees F
He is the only fish in the aquarium.
Any help in this matter would be greatly appreciated.
