20 Gallon Tank given

Okay, so a friend recently gave me his old 20 gallon tank. After wiping it down and cleaning it out, I have bought some substrate (gravel and sand, I did gravel in 70% of tank and sand in other 30%) I also bought some plants at the store today by the name of Cocomba.

I am going to do the fish-less cycle as this appears to be my best option. I have a filter and heater that I will be using as well as planting the plants throughout my tank.

My only quesiton is should I use some of the artificial plants from my other tanks to speed up the process with my new tank or could I possibly take another decoration?

Also, I would like to know some stocking options? I seen a dragonfish today at the pet store and I REALLY liked it. If any one has experience with them and fish that go good with them, I would appreciate it.

p.s: I want to stay away from guppy and gourami as I already have those in other tanks. Thanks

as far as the cycle and plants go, if you plan on going with a planted tank and you start off with a decent amount of plants your tank wont even cycle as the plants will do it for you.

By dragonfish I think you might mean a bichir or a dragon/violet goby? If so I'm sorry to say but they both get too big (up to two feet long!) to be safely housed in a 20 :( They really should have a larger tanks (thinking around 55-150), even when young.

Can you post the dimensions of the tank? 20 gallons come in three different sizes, and that changes possible stocking plans a bit.

We also need to know the gh, kh, and ph of your water to suggest suitable fish for you. You can usually find this information online from your water supplier/city website.

Perhaps the plants are Cabomba?

I was all set to start with a fishless cycle until I realized the benefit of plants... add substrate, water, plants and first group of fish within days. This does require enough plants and fast growers are best. Skip the artificial plants unless you feel that you need a little bacterial help initially, it can't hurt but may be unnecessary.

Yeah the plants are cabomba, that was my mistake on the misspelling. My tap water is around 120-180 ppm gH and about the same for kH. My pH for my water is around 7 - 7.5.

And that is bad news about the dragon goby (that is what I seen). I really liked that thing. I was hoping to find a cichlid that I could house in my 20 gallon, because I like the way they look and they are a little more aggressive which is what I want.

The tank dimensions are 16 inches high, 24 inches long, and 12 inches wide.

I'm looking for opinions. I have a 20 gallon high tank. I planted the tank with Cabomba with sand and gravel substrate and I plan on getting a floating plant later in the week to add as well. My tap water is rather hard, around 160-180 ppm and the pH stays at or around 7.5. I have a Tetra Whisper 20 gallon filter as well as a heater. I will be placing an air stone in the near future.

At the moment, I have a 10 gallon tank that is a little overstocked so I plan on moving 3 of my guppy (one male and two female) to this tank. I was wondering peoples opinions on other fish to add. The gravel takes up about 70% of the tank and the rest of the tank is 30% sand. I want a different bottom feeder than a cory if I can find one that can fit in the tank. I really want something that looks cool at the bottom. I also want some other fish that can go with my 3 guppy that I will be adding.

Any opinions or options will be greatly appreciated.

I've also thought of moving all six of my guppy to the 20 gallon and adding different fish to my 10 gallon. (It also has 5 cory (I know the 10 gallon tank is overstocked with 6 guppy and 5 cory, but the water is clean and levels always stay great)(also why I want to move the guppy or maybe even the cory or just leave them alone and just add to the 20 gallon.

I am stuck on what I want to do.

For an interesting substrate fish, look at the Whiptail Catfish. Click the name for the profile. Make sure it is the common one, species Rineloricaria parva, as there are similar-looking fish that may be labelled "whiptail" that get much larger and can eat plants. This little one doesn't. There is also the "red" variety, in our profiles as Red Lizard Whiptail. These should manage in your water. Corys are fine with them too.

Are there any cichlids at all that can fit in a 20 gallon high tank? Even if it is the only fish in there, I don't know why but I am completely fascinated with them. I wish I had space for a 55 gallon but I just don't right now. But I would love to have a cichlid and other fish but I know cichlid are tough to keep in a 20 gallon.

Water parameters are gH: 160 ppm and pH around 7.5. Temperature is about 76.

The length of the tank, because it is a 20 gallon tall, is limiting somewhat but the cockatoo dwarf cichlid is a close match... pH is near the top of its range, temperature would have to come up a bit. There is a difference between wild caught and tank raised but you can just check with the store which they are. I looked at these initially but my water is far to hard for them.
