Nice. We've got a few tanks scattered around the house. A 55 gallon community tank with a bunch of various types. Glass cats (my personal favorite), about 20 neon tetras, glowlight tetras, assorted platys, a few mollies (including a male sailfin that constantly harrasses the ladies), some African dwarf frogs, four cories, one rubber-lip pleco, some zebra danios, etc. My stepdaughter has a 20gal with two figure-8 pufferfish, while my stepson has a 10gal with three goldfish (including one huge bubble-cheek one). And there's a stray betta.I've got a 55 gallon freshwater tank with assorted cichlids in it and a 29 gallon with some community fish. Half a dozen neon tetras and black-skirt tetras.
Salt water tanks are really cool, but yeah, the cost is prohibitive. And if you lose a fish, then you're suddenly out a lot of money if you can't return it (which you usually can't). I'd like to set up a semi-aggressive freshwater tank, though. I'd get some bigger stuff, like clown loaches and one of those black knifefish. Maybe a peacock eel. You know, some of the unusual stuff that's more likely to draw attention than just be a moving decoration.I've always wanted a large salt water tank, but never been willing to pull the trigger on the high start up cost of it. One of my friends has a 110 gallon salt that's amazing. Water is matured to the point he's got living coral and verts in it.

We have six cats, actually. The best thing to do is to get a tank that sits on its own stand, so the cat won't be tempted to sit and harass the fish. The best thing you can do, and I'm being perfectly serious here, is to get your tank set up with the gravel, decorations, air pump and whatever else you want to use, and start off with something hardy, like a few zebra danios. Keep them for around six to eight weeks and do not add any more fish until this time has elapsed, lest you wind up with what's called "New Tank Syndrome." Zebras are generally pretty tough and can deal with a decent range of water conditions.
This initial period will establish what's referred to as the biological filter, which is the colony of helpful bacteria that breaks down the ammonia and other waste products produced by fish, which build up in an enclosed environment. Once this is complete (a.k.a. the tank has "fully cycled"), then you can start adding in more fish, without undue fear of them dying from the unstable conditions of the water. There are products that treat the water to reduce the waste products in it, but you'll wind up in a back-and-forth routine that's likely to wind up killing the animals you're trying to keep alive.
Trust me; my wife and I learned the hard way about the biological filter and NTS, and we lost a bunch of fish to it. A little patience goes a very long way and will save you a lot of money, not just on fish, but on water treatment products and gas from trips to the pet supply store.
I hope to bring my plan of maintaining a nice aquarium to fruition this Summer. I sincerly appreciate your advice, Deuce. Thank you.
Also, I have a cat. Not trying to be funny here- how am i going to keep him out of trouble with the fish?

What do you feed yours? Mine eats all kinds of shit.
Been in and out of this hobby.
It's just a money sink with potentially a ton of maintenance. Just get a cool ass screensaver and avoid the real thing.
Tetra floating aquatic turtle food.
I also will occasionally give them dried mini shrimp as a treat.
