Jag - minimum tank size???

[PoopSmart]

I agree as well as Imagine the water changes and maintnance you would have to do with a 15" Jag in a 75.

I agree with the room, but I don't understand how the water changes would have to be greater in a 75 gallon? I mean if you used the same filter, then shouldn't the water changes be the same? Or wouldn't they be less? Because 50% water changes on a 75 gallon would be less than 50% water changes on a 125 gallon.

I dunno, I just never understood how keeping a fish in a smaller tank would result in more water changes as long as an adequate filter is used.

Thank you all for the advice. Never ceases to amaze me how much good info is passed on so quickly on this site....love it!!!

My guess would be that it would be similar to keeping a 15" ocsar in a 75 gallon tank. Obviously this is a bare minimum situation, but you can keep big cichlids in a 75 gallon tank. Not that I reccomend it though.

poopsmart, the reason that water changes become more of an issue in a smaller tank is because the same amount of waste is being released by the fish, but in a smaller volume of water it is less diluted. Ammonia, nitrite, and nitrate are measured in parts per million, so while the number of parts of nitrate do not increase, the number of millions does. It is kind of like how if you put a drop of blue food coloring in a glass of water and a drop in a bucket, the water in the glass will be much more blue than the water in the bucket.

Adequate filteration will eliminate ammonia and nitrite just as it would in a larger tank, but nitrate will build much faster in a smaller aquarium making larger and more frequent water changes necessary.

75's alright for females which max out from anywhere from 11-14", male jaguars hit 15-16" easy, so a 75 just doesn't give enough space for them to be comfortable, i'd recomend a 125, or at least 5-6'x18" footprint. and a 75 wouldn't give enough room for tankmates with a female

I agree with XR. 5 x18" footprint would be my minimum for a single grown male.My boy will except tankmates in a 6' x2' footprint fairly easy but not a chance in anything less.

Listen to GreenTerra she has one of the biggest Jags on this site. By the way how big is your Dovii now?

LMAO.Cross127 .Do I sound feminine?Gender is male incase that is not a misprint.The Dovii is 10+" now and just starting to get some bulk now.You can see him here. http://www.monsterfishkeepers.com/forums/showthread.php?t=109207


Here is a pic of my Jag.He is in a 180 gal.In all honesty I could not picture this fish in a tank less than half this size.Especially considering he is still growing.

Ooooh ok, thank you for explaining that. I thought it was parts per million were like moles. So I figured it wouldn't matter becasue the moles would be the same, but the molarity would just be higher in the smaller tank (like 1 mol of HCL is one mol of HCL no matter how much water it is diluted in)

Thanks for that, that makes since, thats why its easier to maintain a larger tank becasue its ahrder to contaminate it then.
