Tank For Angelfish?

[trietpham]

hello everyone, i'm new to this site. thanks a lot for any help and advice  
i recenntly set up a new tank last week. it's 60cm long, 50cm wide and 40cm tall. i've already planted plants in it: amazon sword, sage, water lily,.. and some floaters: water hyacinth and water lettuce (it's an outdoors tank actually). so far, the water has been green for a week (but not so cloudy, i don't expect an outdoors tank to be crystal-clear 

but i could still see th)rough it). plants are starting to grow, i've put in some shrimps (ones for feeding predatory fish) and babies molly to encourage the cycling process, so far, they are doing well. i'm planning to get some angelfish (4-maybe

 

 

 

 - to pair up). i know that they are not so easy to be kept and require good-conditioned water. however, last time i put a pair of ram cichlid outside and didn't look after them very much, but they spawned and 1 of the babies is still alive now, so i want to try with angelfish.
what do you think? is the tank not tall enough for them and/or is it too small to keep 4 angelfish? pls let me know, i'm receptive to all your advice.
tks a lor
p/s: the tank is on the top floor and i live in a tropical country (if it makes any difference from temperate countries)

I'm afraid your tank is too small for four angels I wouldn't even put one in it.

so disappointed, i really want to keep them

. anyway, there is no filter in the tank so i guess it's hard to keep them. could you recommend any other cichlids, just love their habits, ram maybe?

Angels are nice fish!
 
What is your pH?
 
If you want to successfully keep tropical fish and if you don't want to do a lot of water changes, you will need to get a filter and you will need to cycle it (link in my sig). 
If you don't want a filter, you will need to do daily water changes of at least 40% to keep the ammonia down.

i think that the bacteria eats the amonia, aren't they? unfortunately, i don't have the testing kit.

that's a lot of water. ttks for your advice anyway

The majority of the bacteria grows within a filter, hence the need for one.

You could try to keep some dwarf cichlids, buttttttt : Most species defo eat shrimp !!! Couldn't you buy a small filter. The bacteria that "eat" ammonia and nitrite are 95% in a filter (only can live in oxygin-rich - flowing water).
 
For angels your tank is too small indeed (1.20 cm X 50 cm x 50 comes first).

it's not the problem really: the shrimps are meant to be live food for predatory fish, i just bought them to test if the tank is suitable for any creature yet.
you know, i'm kinda "naturalistic" (i mean i want a "natural" tank 

), so i don't want to put a filter in the tank (and it also costs a lot, just think of the electric bill 

).
so DubbleDutch, it's ok to keep ram cichlid in the tank, right? and the water is so green now (i know, it's inevitable if your tank is outside), but anything i can do to reduce it?, i've put in a lot of moina to eat up the algae.

Surely a natural tank represents their wild habitat - most fish live in running water so the filter simulates this?
Yours would be a stagnant puddle. Plus the water will need to be flowing for decent oxygenation.
Filters cost next to nothing to run.

If this tank is outside is it heated? Aside from not having proper filtration temperature fluctuations can kill tropical fish.

Agreed!

well, actually i found this site and i do really hope that i could make one

actually, i live in tropical region, so i don't have to worry much about the tank being either too cold or too hot (there's lot of floaters and shade actually)

If you have lots of fast growing plants and you place the tank in the right place it is possible. You would still need to do a weekly water change of around 50% to make sure that the ammonia doesn't get too high (unless it is very heavily planted, the plants won't eat all of the ammonia).
 
Also, a filter would still help, if you don't want a filter then a power head would suffice. The reason why is because the fish will want some water flow and so will the plants, water movement helps distribute the nutrients for the plants.
Water movement will also increase the oxygen levels. The higher the temperature, the less oxygen in the water and the higher the need for water movement.

thanks a lot

Comments like this aren't really helpful, do you know how much it costs to run a filter in vietnam? how much electricity might be there? I don't.
 
It's entirely possible to run a healthy tank without a filter. http/www.tuncalik.com/2009/09/biotope-in-my-study/
 
But yeah your tank is too small for adult angels. heh
