20 gallon

I decided to upgrade my 10 gallon to a 20 high. The stand the 10 is on can hold a 20 high but not a 20 long. I got the tank on sale and only had to buy a 5lb bag of black sand and a nice piece of mangroove root I found. Already had the glass top, a cycled AC 50, heater, 15lbs of black sand, and...

Whats the best light for a 20G long? Right now I have a cheap led strip light on mine and the only plants that seem to enjoy it are anacharis and they grow very slow. My biggest concern is price, I don't have a lot of money to spend on a fancy light so if anyone knows a good light that isn't too...

Can I keep one Siamese algae eater in a 20 tank?

Hi!, I have a fully cycled 20 gallon, in which I currently have 4 Glofish Tetras (one didn't survive the tank switch from 10-20 gallons) and I currently have a Dwarf Gourami and a Bristlenose Pleco in a 10 Gal quarantine tank. Ideally, I would like to have 6-7 Glo Tetras, the Dwarf Gourami...

I have a tall 20. The fish I have in there are mainly bottom to middle of the tank fish. Im looking for a fish that will stay at the top of the tank.

Yes, the exact same 20 gallon before. I found another that is pretty much 2, 10 gallon tanks on top of another. I went to my LFS to find some fish to put into the tank and became completely overwhelmed. I had so many options. I decided to get 4 rummy nose tetras. I want to get 1 more. to add to...

I have a male mosquito fish who is all by himself. I would like to move him into my tetra tank with 8 tetras and 3 long finned danios. Will the mosquito fish attack the fish? I also have a 20 gallon tank that I think I am going to convert into a tiger barb tank. Would he be better off in this tank?

Hi, I have a tall 20 gallon tank. I was thinking of giving my 3 guppies and white cloud minnows into the tank. However, I was thinking that I could do some other schooling fish instead. One fish that instantly crossed my mind: Tiger barbs. I love these fish and they are the size I find...

I recently have gotten a new 20 gallon fish tank. I am going to switch my 3 guppies, 3 white cloud minnows and 4 inch goldfish into the tank. I have always had a fascination with angelfish. I was wondering if I could put just one angel in the tank with the other fish I have. Is it possible...

Hi, I recently got a new 20 gallon tank. My hopes for this tank are to transfer my telescope goldfish, 3 guppies and 3 white cloud minnows into the tank. I would also like to either get new fish for the tank, or add more fish, like guppies and white cloud minnows. I was also thinking of another...

Alright so long story short, I now know why people don't like hex tanks when compared to normal rectangular tanks. After I re-homed my angels I considered trying a crayfish or maybe a couple of African Clawed frogs but I think I want to give reptiles a shot. My tank dimensions are: 21" height...

I have had my first aquarium, a 10 gallon, for about a year now and have had a lot of success, so I am going to be upgrading to a 20 gallon tank. My tank currently has a dwarf gourami, 5 neon tetras, 2 otos and 2 ghost shrimp. I would like to add some more fish once I get my new tank set up and...

I would like to know how many baby African Cichlids I can safely keep in a 20 gallon tank. I plan to upgrade to a 75 gallon tank, as soon as they grow in size(aprox. 6-8 months). I am currently have 1 demasoni, 1 bumblebee, 1 yellow lab, 1 tropheus duboisi. I appreciate all of your feedback in...

Hey everyone, I am currently stocking a 20 gallon long and I was wondering if I could get some advice on my stocking ideas. I checked on Aqadvisor and they both seem to check out. I am running a Fluval 206 canister at the moment and can add a U4 internal or C4 HOB if needed. 1) Barb Tank: 5-6...

Hello, I've got myself a new tank after many years away. It is a planted 20G long with a single aquaclear 20 and I am having trouble coming up with a good way to increase flow and or filtration. I'm currently cycling the tank so want to get this sorted before I get fish. I was thinking Harlequin...

Hey guys! I'm in the process of cycling my 20gal high freshwater tank with AquaClear 50 HOB (almost done!!!!!!! double-checking later this evening to see if 3ppm NH3 were cycled to 0 in 24 hours so fingers crossed!). I planted what I thought were some hardier plant varieties about 3 weeks ago...

Hello everyone, I'm fairly new to the Aquarist hobby. I bought a betta fish for my desk at work, but didn't want to put him in a bowl. Instead, I bought a 2.5 gallon ready-made aquarium from Tetra. I decided I wanted to do a planted tank, so I upgraded to a 5 gallon tank, and then a 10 gallon...

Howdy! I finally got my 20g long tank set up and cycling last night, so I thought I'd share some pics. Right now it's just water, rock, and wood (and one tacky ornament). Plants should be going in next week. The specs are these: Coralife 65 watts 6700k CFL light Aquaclear 50 HOB filter, with...

Hi guys, I've just redone my tank to add plants and junk, but my questions is, Im assuming I need to take the oxygen bubbler out because the plants need CO2 not oxygen, and they will provide oxygen for the fish themselves. But I'm thinking I need to provide CO2 for the plants? how does that...

Hi Guys, I am redoing my 20 gallon High tank, and trying to find a nice centerpiece fish to put in it. Im going to put it with some of the larger sized tetras, its going to be a planted tank when Im done. Looking for ideas on a Colorful centerpiece fish. Any recommendations?
