Establishing a New Tank, Current Flow

Good Day All,
I recently got a fish tank back after not having one for about ten years. I am super excited about getting some little swimmers and I have some questions about my set up and what fish would be the best for it. I have an 18-gallon hexagonal tank with a Fluval AquaClear PowerFilter HOB and a Fluval Q.5 Air Pump. I chose to use a sand substrate (which I learned will stop a filter so I had to get some prefilters) and 4 fake plants. I have a heater for it but have not set it up yet (wondering how necessary it is). I set up my tank and haven't gotten any fish for it because I wanted to establish it and make sure everything was in order and was worried about leaks because I had to reseal it. So now that my tank is set up I look at it with excited eyes but I worry that the current will be too much. Because its tall and not wide I see that the air pump and air stone are putting out a decent current I am not too worried about the filter because it has an adjustable flow and is at the top. I am concerned about the bubbles though because of how narrow the tank is. I love my setup but worry that the water movement might be too much for fish. So, my questions are; is it possible to lessen the flow of air, if not what freshwater fish like a strong current, and is a heater important?

Welcome to the group. Nice looking tank.

You can put a adjustable valve on the air line they allow you to turn down the air flow and that will help with the current.

Some fish like the higher current Cory Cats (most are 2" or less) would be a nice choice they like to school so you would want to get 5-6. Then you could pick 2-4 more fish that stay higher in the water. Off top of my head 5-6 Black skirt tetras or maybe 8-10 Neon tetras, but I'm sure they are more.

The taller tank does limit the number of fish you can have but you can have a great tank just have to pick the right fish.

Thank you. I will check on the valve when I go to the pet store. I was really hoping I could get Mollies, Danios, Platies, or similar fish. I knew that the shape and size would be a slight problem.

Here is a link so you know what to look for.
Imagitarium Aquarium Air Control Kit | Petco

Any store selling fish supplies will have them.

Danios would be a good choice I think they like to school to in groups of 6-10. Mollies are great fish but they get a little big so I would stay at 3-4 max, platies are a little smaller so maybe 1 or 2 more. In a normal rectangle tank you could do a lot more fish but Hex tanks are cool I have a small one but they are harder to find.

My family got this tank 15 or so years ago and when we moved we gave it to a friend who gave it back when I moved back. When I say 18-gallons people get confused. I am hoping the 1-gallon per full grown fish still applies. I want to add color by fish instead of adding decor. I think its perfect as is right now.

18g hex isn't too common for sure.

The 1" per gallon rule doesn't work, we have learned over the years it's a god starting point but not always good. It really comes down to the shape of the tank, for example a 20g long tank and hold more fish then at 20g High tank. The difference is surface area, the long tank has more so allows for more gas exchange meaning it will house more fish.

Another good example is the 55g tank is 48" long so you can keep lots of 10-12 african cichlid (5" fish so 60" total) because they like to have the longer area to swim in but the 40g breeder tank is only 36" long and has more surface area so you keep 30-40 guppies (2" fish so 60"-80" total). So you can see the 1" rule can get you close it has to be adjust for every tank.

Platies are a good choice, they are come in blue, orange or yellow so you get lots of color and do well together. They will eat some of the fry so you shouldn't be over loaded in fish after a few months.

Mollies do have the colors that platy do, I have some black mollies and depending on the tank they can be hard to see.

Oh my, I didn't know that about the size I will have to keep that in mind. I will probably only get a few fish at a time to start. Maybe like 5 rosie reds.

We are here to help just ask the questions you think of. Rosy reds minnows are nice fish too my guess is you can do 15-16 of those so lots of action in the tank.

Thank you so much. If I have any questions I will ask. I used to get 100 rosies at at time and loved watching them school.

You are welcome, glad to help


I have a small group of 11 right now but I'm hoping this summer to breed them in a tub outside so I will have hundreds this fall.
