Has anyone ever had a clay pot change the water chemistry in the tank? Is this ok to put In my tank?

Got my 75 setup and will be getting a senegal bichir, a peacock eel and a zig zag eel soon. I want a larger schooling fish so I was thinking clown loaches but they will eventually outgrow the tank, bala sharks also came to mind but I'm not sure how fast they would outgrow the tank, then I came...

I just picked up a 90 gallon aquarium and it came with a sump setup for SW with a skimmer and I think it would be easier to start over rather than reconfigure it. I'm using a 20 gallon aquarium because unless I make one myself that's all that will fit in my stand. As of right now we are...

I noticed this white clear cloudish stuff on my driftwood only today and wasn't sure wat it is? I'M not gonna lie I have been over feeding a bit in order to have my roseline sharks eat a bit since the 15 platies demolish everything (they'll be gone in a week or 2) I'm gonna do a water change...

I'm getting close to setting up my tank and one of the fish I want Is a small school of rose line sharks (Denison barbs) but I also want a white crayfish. Would my barbs be safe with a cray fish around? Would it be best to let my barbs grow larger say 4 inches or so?

After almost two years (easily over a year and a half) of reading and studying and more reading I have started a custom tank build for a stingray. Thanks to this site whom I've just joined but read over and over again I feel comfortable in taking care of theses beautiful fish. I just wanted to...

Hello I'm new to MFK so I apologize if I'm doing this wrong. I recently bought a 55 gallon aquarium and not sure what all I can have in it, I'm looking for a community type aquarium but would be open to single bigger fish suggestions. I was looking at gouramis and thinking one good size one...

So I put a half inch sheet of styrofoam under a 240 gallon acrylic tank and I have four bulkheads in the bottom of the tank two out and two in. My question is are the bulkheads going to losen up as I fill the tank with water?

The eels from lake Ohrid travelled for millenniums a mysterious journey from Lake Ohrid to the Saragasso Sea. In the second half of the 20th century two dams were built on the Macedonian part of Drim river and four dams were built on the Albanian part. This video shows the migration of the...
