30g tank opinions wanted
 
My 30g tank has been cycling, and is now nearly ready for fish (in a few weeks ready) so what I am looking to move into the tank;

5 Gold barbs
5 java or cinnamon (not sure which, Petco strikes again) loaches
2 Dwarf Gourami's (been with me for almost a year, and doing well)

these guys have been living in some cramped quarters (some 10g tanks, now they all have to learn to live together)

Thinking of added 5 Neon Tetra's. Yes or No?

right now the fake plants abound, and have two shipwrecks to swim around...

I want to move to some live plants, but what would you recommend? swords? top floating? Thank you for your opinions!

water: nitrate (NO3) 35ppm
nitrate(NO2) 0
hardness 75
alkalinity 75
ph 6.8

I use bottled drinking water from the store.

Well, the Golden Barb is a cooler water fish than most, 75 is listed as their maximum temperature with ~69-70 being much better for them.

The loaches are probably Black Kuhli Loaches (Pangio oblonga) and this is a case where common names don't help as the same fish can be called many different things causing confusion. They like a little cooler water, but closer to a normal range. 70-78 with being in the middle of that best (74). 5 is the minimum number of these you should have.

The Dwarf Gouarami are a more typical temperature fish, with 73-82 and again a temp in the middle of the range being best (78).

Neon Tetras are the same with temperature, liking the warmer water. They will need a larger school than 5 though, I wouldn't go less than 8 with them. As a small fish, they really do best in large schools.

So to answer your question, I would not mix all those fish due to temperature requirements. Having your tank at 73 or 74 would be your only option, but you'd be at the extreme for both the barbs and the gourami. You may also have an issue in the summer if you don't keep your house under that temperature.

Live plants are great and yes should be used, there is rarely a situation where they shouldn't be used (a few fish will eat almost all plants, and a few are too active and rip them up). With loaches you may have a harder time with stem plants (they may uproot them when rooting around) but Sword or Crypt plants would be just fine. Floating plants are excellent as well, as most fish like the shade they provide (plus they are faster growing, and thus have the biggest affect on water quality).

Just so i am clear to readers:
Right now the barbs and loaches are together in one 10g tank. The temp is at 77 in their tank. They are doing fine, other than being cramped while waiting for the 30g to finish cycling.
The groumi's have been in another 10g tank with a temp around 77 as well. I have had them for 1 yr. They have been doing fine as well.

And if i understand the reply correctly you are saying; the larger tank would be to much stress water temp wise to put them together? And forget adding neons...

real plants are always better. just had to go with what i had at the time...

Your 2 DG are doing okay, so that's good. Can I ask if they are male or female?

Since you have scoling species already, I would skip the Neons and increase the size of the Loach and Barbs. I would have to play around with numbers (but I'm tired so I will leave it to the others), but you might be able to increase the DG too.

See if you can buy a bulk of plants on here from someone to help absorbe amonia as well as break up light of sight in the new tank which will cut back on fighting. Add PLENTY of hiding spaces and if your current decor doesn't cover it, throw in glass jars and tubes (wash with vinegar water and rinse well!).

Any idea what you will do with the old tanks?

They can look fine, but that does not mean they are free of stress. Being outside their temperature range isn't something that would cause sudden death, certainly not from only being 3 degrees out of it, but it is something that takes its toll after months or years. More along the lines of a fish living 3 years versus the 5 that is normal for their species.

I would exclude either the barbs, or the gourami and in whatever tank the barbs are kept, lower the temperature considerably.

As for real plants, they're not a requirement, they just offer numerous advantages over plastic. Plants use Ammonia as a source of Nitrogen, in fact they'll use Ammonia before bacteria can. That means far less nitrite and nitrates get produced in tanks that have live plants than those that do not.
