Yes I agree they do fine with a little salt, also don't over dose your chemicals either it is really easy to do so in a small tank
I used to change 50 percent of the water every week and clean out all of the gravel when I had my 7 gallon nano. It was a little overcrowded but my fish did fine. I do a 40 percent water change weekly in my big cichlid tank and clean all of the gravel, but that is just me I like to have very low nitrates and 0 nitrites. (and cristal clear water!)
what chemicals are you referring to? am i supposed to be adding something else to the water? or do you mean the dechlorinator? so ill plan on doing a 50% change every week and vacuum all the gravel. how often should check the amonia, nitrite, and nitrate levels?
my tank is going to be a little overstocked. im going to have the ones i have now (one guppy, one balloon molly, one dwarf platy) plus 3 pygmy cories and one sparkling dwarf gourami. they are all less than one inch except the molly and guppy.
The vacuuming 1/3 only of the gravel is probably a hangover from older times with less efficient filters, where you probably did want to be careful to keep every single bacteria. Modern filters are more efficient and it is now thought that a relatively small proportion of the bacteria live in the gravel anyway, so vacuuming it all shouldn't be a problem. I do find with corys that it is VERY important to keep the gravel clean as they can easily get bacterial infections from dirty gravel, particularly in hot weather.
oh, thats important info to know, thank you
No that is all you really need chemical wise. (Maybe a ph buffer if your ph is too high or low in the tap water, although most fish will adapted anyways.) I would recommend testing every week for the fist month before and after water changes just to find out the effect of the water changes and also to regulate how much water you need to change every week for your particular stock. After a month I would stick to testing every week before your water change. You need to know if your tank is holding out between water changes. You don’t want heavy nitrate or nitrite spikes. Test your tank if any of your fish start acting weird and of course if any of your fish should happen to die.
DG's get about 2 inches sometimes more, mine have never gotten bigger than 3 inches. They are nice fish! But remember they all have there own personalities and some may be aggressive. Your tank is very overstocked however I have seen worse, as long as you keep your water conditions under control it should not be a problem. (you are getting hardy fish, except for the corys of course. I would get extra filtration. Might I suggest getting a German ram instead of a gorami? They are much more predictable in behavior. I think the stock would probably work anyways. A little dwarf frog would probably do well too. Also don't forget to add your fish in slowly, don't add them all in at once. It is too much of a stress on your tank, the bacteria may not be able to catch up fast enough and your fish will become stressed and floating targets for parasites. (Like itch) It is a common killer, some people get lucky and some people don't. Its always best to be cautious!
Good luck with your tank and take care if you need any help don't be afraid to ask. I will give you my honest opinion based on experience. Its not practical to be an idealist but you should think realistically when stalking a tank don’t take any huge risks. I actually have a blood parrot in my big African cichlid tank because he was beating up all of my south American cichlids and he is doing fine, so you know never know how a fish will react for sure.
thats what i was told by the people who gave it to me....
i just tested the water and it comes up 0 ammonia, 0 nitrite, and 10 nitrate.
i think that means healthy water but can anyone verify that for me?
Yeah that is great test result, your tank is doing fine!
Nitrates are ok if they are less than 20. (only as a guild line someone else may say higher or lower than that.)
