Post some pics of your aquariums. Here are mine. On the left is the 55 gal and 20 gal on the right. The 20 gal with sand and canistor filter. Also with vinyl black backing. I have the vinyl on the 55 gal as well.
Water added and waiting for the ammonia and nitrate levels to come down. Then it will be ready for fish.
I'll get some pics of the 55 gal later. In that tank I have 2 Silver Dollars, 2 Congo Tetras, 2 Gouramies, 2 Red Shoulder Severums, 1 Spike Head Pleco, and 1 Clown Loach. I would like to try and build an acrylic tank one day. Oh, and one of my favorite shows is Tanked.
I've seen some really nice freshwater tanks too. It's all about fish selection. Of course, saltwater is where the colorful fish and cool sharks live, so that's tough to beat. Isn't upkeep on a saltwater tank a pain in the *** though? I'm flying to keep my dog walked, I'd probably kill saltwater fish in record numbers.
And goldfish are extremely difficult to keep alive. They've gotten more sensitive to water conditions than the ones we had growing up.
I would like to do a saltwater tank. But it is very expensive. And you have to keep up with it almost every day. The filtration is what so expensive. The wet and dry filtration, protien skimmer, UV sterlization. Among other types of filtration. And then if you want to go full living reef saltwater. That gets even more expensive. A 100-200 gal saltwater could cost up to a couple grand. I do need the UV sterlizer for my tanks though. It keeps algea from growing.
The thing about goldfish. Once you have them, you can't put any other fish with them. They put out a toxin in their waste that would kill other types of fish.
That's what I figured. I had a guy come into my office last year trying to sell me on a saltwater tank. I don't remember all of the details, other than it was going to be a monthly fee that I remember being high. They do look good though.
