25% Water change

I cleaned tank and water parameters are:
Ph 7.6 tap, 7.6 tank, high range 7.4 tank
Nitrates 40 ppm
Ammonia 0 ppm
Nitrites 0 ppm
4 - 8 dGH 70 - 140 ppm


So in light of all that and the gh & kh in previous post what would my best choices for fish be?
I want peaceful fish with no fighting and tormenting each other.
I currently have 6 rummy nose and 1 pair of turquoise rainbows
also 2 clown loaches, but I will return them for something else tomorrow because they need to be in a group of at least 6 and they grow to be 12 inches long which is way to big for my 72 gallon tank. Any and all suggestions appreciated.

To answer your question in post #60, yes, you are correct, you have soft water. The low KH means it is slightly buffered, so the pH should shift more easily as the tank matures, becoming slightly acidic.

To post #61, soft water fish will do well. If you like the rummynose, get more; a group of no less than 15 is best, even up to 20 in your case--this is a fish that needs larger groups to be secure, and given its schooling/shoaling behaviour, remaining in a group almost continually, it is a lovely fish in a 4-foot tank well planted.

The rainbow Melanotaenia lacustris is a bit of a problem. This fish is not in our profiles, but here is some info from which you will see it does not do that well in soft, acidic water:
Lake Kutubu Rainbowfish (Melanotaenia lacustris) - Seriously Fish

It would probably be OK at present, the GH is a tad under where it should be, but the pH is fine. But as i suspect the pH will gradually lower--and it would certainly be better for the rummynose if it does, as low as it can go won't hurt them--you might want to rethink this combo.

Adding other fish will obviously depend upon your decision above.

I messed up then. At the LFS they have all these fish together in one tank. I went today and got boeseman rainbow pair and 2 redline sharks. I got these because they are all living together in one tank at store and have been for years. They even have electric blue jack demseys, rams, congo tetras, rummys, algae eaters, redline sharks, all of the different rainbowfish, something else I'm not sure what is. I hope mine works out. I do intend to add to the rummy collection I'd love 15 or 20 maybe more. If all these don't do well I will just stick with rummys. I was going to get some corys but they are always out of them. I guess they go fast. I guess I will not get anything else for awhile to make sure how these are going to do. I had a pair of the Lake Kutubu rainbowfish before and they did well until my heater over heated while I was on vacation. I lost all my fish then.

I did find out that my gravel is Estes Spectra Stone Gravel.

Also I don't have live plants, I have artificial ones.

First off, the tanks in any fish store should never be taken as "correct." Things are very different in fish stores from a home aquarium (or should be). Fish in store tanks are usually under stress, and as I have written many times in various threads, this can sometimes increase aggression but often it is the opposite. Put the fish in a good environment suited to it, and if it is healthy it will settle down and its true behaviours will likely flower.

Second point on store tanks is that most adjust their water to be sort of in the middle, thus they can keep (for the short period it takes to sell them) fish with differing needs in much the same water. The fish may be lacking in colour, or again stressed a bit, but here too they will return to their natural colouration once they settle in a good environment.

The Boeseman Rainbowfish is in our profiles, click the name for the data; it needs a couple more. And the Roseline Shark is also in our profiles under the common name Denisons Barb or Puntius denisonii and it too needs a group, it gets 6 inches and will likely eat rummys, and it needs a larger tank. All as noted in the profile. Your tank cannot support both species in adequate stocking numbers, plus there is the predator issue with any smaller fish.

I really cannot stress enough the value of thorough research before acquiring fish. I have learned this lesson the hard way, by losing fish or having to even destory some to keep peace. I now have two maxims that I never allow myself to ignore in a fish store: 1, I never buy any fish I do not know about; if I see something new, I note the scientific name and come home and research it, then decide to buy or not. And 2, I never buy any fish that will not, at full mature size, be perfectly right for my existing tank; this way I never have to worry about larger tanks down the road.
