Hello Everyone,

This is my first topic on this forum. This is my first forum of fish and aquarium and I love it very much, Everything here is too much good and nice and great and one more thing I don't have words to express. (Please Don't mind my language grammar and spelling)

So I have some questions about the vertical fish tank. Since we don't have much space in our room for horizontally tank, that's why I decided to make a vertical aquarium by my own. When I was making I don't know anything, I only know that I just have to put the fish in that tank and it's all done. But when the making is in progress I started to read some articles and topics in this forum. And then I know that it is not the thing that you just put the fish in the tank, but there is a lot things to do and to make the fish alive, happy and healthy. I have one picture of my tank and you can see that in my profile.

My tank is 3 foot height, 1 foot width, 1 foot length. That is about 20 gallon because I left some part empty. Now I have 11 fishes in it and I have under-gravel filter, so from here the question start :-

Do I need more space, will fish be ok in this, do fish get enough space to swim, what else I can do to make my fish health and happy.

I know the rules now about the fish that how much water they need normally. But after some time I will be making another tank which will be of 403.95 Gallon. And I want to keep some of my old fish in it with some other new fish too. But since this tank will be a lot much expensive so for sure it will take time.

I want to know what else I can do so that no fish die, till now only one has die and about 28 days has gone. I am happy that my fish are alive and I will try to make them alive how much I can.

I can also donate my fish to pet store if my tank is over crowed. So please help me and tell me.

Thanks in advanced bye bye take care....

What type of fish do you have? Some fish stay very small and will do fine in a tank that size, others will quickly outgrow your tank.

Goldfish/carp are unsuitable for that tank

Twenty gallons is not a lot of space, but the SHAPE of the tank is going to be even more limiting. Not only are all medium to large fish out of the question (goldfish and carp get to be HUGE), but so are small fish who like to have a lot of room to swim (like zebra danio). Also, your small amount of surface area is going to provide a much smaller space for oxygen exchange. This will also limit the amount of fish you can put in the tank. I think a group of guppies would be nice.

always good to have a tank that is long and wide rather than tall

the key to a fish tank shape is how much area...much better than having a 20 gallon long than a 20 gallon tall...it gives the fish much more room to swim about...angel fish like tall tanks, but the fish which do like or can handle taller tanks are small and in between

so the next tank you get, be sure to focus on long and width...and if not width, at least long....so overall, the length of the tank is what matters most

well I do not think your fish may die, but the fish are certainly stressed

if you can purchase a minimum size tank of 40 gallons long in about 90 days or sooner, I am sure the fish would thank you

I realize our financial situations are different, but if you do upgrade, try to get as close as possible to a 55 gallon long tank (I believe 55 gallon long should be the minimum size tank for a beginner)...but if you can't, see if you can get a 40 gallon long

let us know what you decide...any questions we're here to help
