I have a 75 gal
with a Tilapia Buttekoferi. He is about a year and a half. I got him as a baby and now he's about 10 inches. He is alone now since he became very aggressive with his tank mates in a 90 gal
(African Cichlids Lake Malawi and one parrot).
A few days ago my son purchased a medium sized managuense. He put him in his 90 gal
that has two Oscars along with a group of gold fish feeders. All the gold fish died upon impact and the managuense went into shock. I am aware of my son's water conditions. He doesn't take care of his water the way he should. Trying to save the managuense he put this poor fellow in another tank (no filter, water dirty and cold) then from my yelling, he put him in my 75 gal
with my Tilapia. I did a partial water change and put in conditioner with extra slime coat. This fish is in BAD shape. His eyes are swollen, his fins are torn but he is still alive. I am hoping to nurse him back to health. I am wondering if I should leave him in the 75 gal
. He is resting upside down next to a plant. If I disturb the water he'll swim but then quickly goes back to rest near the plant. He looks so bad but just in the fins and eyes (there's also white stuff like foam covering his eyes). His body looks okay. I'm not giving him back to my son. I will probably tell him he died then take him to the pet shop. His Oscars are used to poor water conditions but not all fish can stand it. He feels he can change the water every 4-5 months. He doesn't do partials, he does the entire tank. I get upset when I see the fish and will do a partial myself but it's not enough. The Oscars are fairly large but they don't look as good as they should in my opinion. On my own tanks I do partials weekly and check my levels on both tanks daily.
Should I leave the managuense in the 75 gal
and just keep doing partial water changes or put him in a fresh tank (10 gal
) and treat him in there? I am not sure about the 10 gal
because he may not have the bacteria needed. My Tilapia isn't attacking him since he's hiding in the plant and even when he swims a little, the Tilapia just looks at him.
