Is my filtration OK for large cichlids?

  • We are currently upgrading MFK. thanks! -neo
I'm curious because both are commonly said to be able to live life in a 75.

I won't deny you can do it, I'm sure I could keep an oscar in a 29G for life, but it'd be a crappy life for the fish. and 15" in a 18" wide tank is the same thing, just a difference of degree. I can simulate the extra swimming space with directional current several times a day, so even though it can't turn around it would still be exercised.


Taking measurements and quick calculations I see about an average 12 -13 inch fish, not the 16-20 inch monsters that are being claimed as normal.

I never claimed it was normal, simply how big my fish got. and since I had to take him to a LFS , I've always planned for the top end of fish size. and I've never had to get rid of another fish because it got too big for me to keep.
think of it like glass thickness, you don't NEED to go with a safety factor above 1, but you're sure glad you've got it when you need it. and if you don't need it, consider it an increase in quality of life for the fish. when is a bigger tank a bad thing for a fish?
you do want your fish to have a good life, don't you?

I haven't seen anyone say 16"-20" is normal, just possible.
 
You have no idea what i payed for him and its not cheap to feed him properly to get his color back. Your not really in any place to talk ****. You dont know enough info on the situation.

Probably not, I can see though that you don't practice what you preach regardless of your excuse.
 
The width is not 60 but 24"? Thats ridiculous. Its a 5' tank. The oscar is about 15" theres no tales. You asked for a picture i provided one. You can nit pick and cry all you want. 60" tank. The fish takes up 1/4th of it. Nuff said.

No, you provided exactly the kind of picture I said I didn't want. Taken at an angle with the fish at an opposing angle, nothing of a standard size to verify against other than your eyeballing guesstimate. Now it's nuff said.

.

So your telling me a 15" fish CAN NOT turn around in a 18" tank?

When i first started to keep fish i bought 2 oscar fish at petsmart and kept them in a 35 gallon tank. They both reached about 9 inches. One day i decided to google oscar fish found out they need a bigger tank. I ended up getting a 500 gallon custom order tank from my local store. I put both oscars in there. They were very happy, but i was Not happy at all. The tank looked empty with 2 oscars. So i decided to get rid of them. And i got 20 dollar store credit for them. I bought 2 jaguars. 2 red devils. 4 red tigers. 1 black belt. 1 pastel cichlid. 8 convicts. 4 jack Dempsey 2 flowerhorns. I spent a couple of dollars. It was all cool till they started getting bigger. They would fight night and day. I have learn so much now. I just think that a 90 gallon is fine for 1 oscar. 2 will probably fight with each other.

Don't recall adding your name in to that comment about quoted oscar size, just going off the averages of what people claim but never back up with proof. Had a guy swear he had a 20 inch oscar, but again no pics. His excuse, he didn't think it noteworthy because oscars commonly get that big in the home aquarium with proper care. There's a a youtube video of a guy claiming an 18 inch oscar raised in a 40 gallon tank it's whole life. Funny though, when the oscar turns neither tail nor nose touch glass. Either the widest 40 on record or an extremely limber oscar. In the comments are claims of 20, 22 and 24 inch fish. None of them have documentation either.

Don't get the not having a camera bit, but then again I've always had one since the old Kodak instamatic 110 with flash cubes.

Still waiting on actual verifiable measurements of one, not camera tricks and guesses.
