Should I use some kind of planted aquarium substrate? I have 2 harlequin rasboras, 2 rosy tetras, (plan on getting another one or is it at least 4 that they need to feel safe together?) 1 orange neon tetra, 1 yoyo loach. (I think I need to get more of these too) and the redtail shark and danio that will be going back to the fish store. Do I need to get more rasboras for them to feel safe? I would like to get a "shoal" of true rummynose tetras and and lemon tetras. With all the extra fish I need to add for my current fish to feel safe and the new additions that I want to make, will my tank be overstocked?
If you like the appearance of the gravel you have, no need to change it for plants. Plant substrates have nutrients that assist in plant growth, but they are not essential to a nice healthy planted aquarium, as my plain gravel tanks clearly illustrate. Liquid fertilizer will be sufficient. However, if you want to change the look of the substrate, then for a small tank like a 10g I would consider an enriched substrate like Flourite or Eco-complete. These are obviously more expensive than plain gravel or sand, but the amount for a 10g would be one bag so not too much to spend if you like the look. You can get these in natural browns and black, both of which are very beautiful with plants and forest fish that will really colour up with a dark substrate (if your present gravel isn't dark).

On the fish, I must suggest that you make some decisions. In a 10g you simply do not have space for all those you've mentioned, with just what you currently have since I agree they need increasing in numbers.

Tetras and rasbora are shoaling fish that should have a group of five or six, no less. I have a group of Rosy Tetra, and while they are beautiful, I think they are too much for a 10g; a 20g long is in my view minimum size for this beautiful fish. They have a social structure that needs a group of males and females, 3 males and 2 females would work; they are not overly active by comparison to some fish like danios, but they attain 1.5 inches and need some space to move around and interact. Check out our fish profile (click the shaded name).

A group of 5-6 rasbora would be fine, with a bottom fish. And on these, the Yoyo loach you mention needs a group of at least 3 and this is going to be crowding them in a 10g. This species attains 6 inches in length, and needs space with hiding spots as mentioned in our profile although the size is not listed yet. Loaches are highly social fish; our profile does recommend minimum 3 or preferably 5, but in a 55g tank. If you like the yo-yo loach, a good replacement would be the dwarf loach, Yasuhikotakia sidthimunki which is very similar in patterning but as the name suggests smaller, 2.5 inches, and a group of 4 or even 5 in your 10g with the group of rasbora would create a nice SE Asian aquarium.

Expanding the fish you have, or replacing as with the loach, is going to fill your 10g tank. I would not add rummynose tetras to a 10g, they need swimming space. Interestingly, I just noticed neither species is included in our profiles; I was certain I wrote up the Rummynose profile, must have been for a thread I guess--will have to rectify this oversight.

Thank you for your help Byron. You're awesome. What would you suggest I do with my two rosy tetras? I have 30wpg over my tank right now and I was reading your plant guide and you said that 1 wpg or less is sufficient fir the low tech aquaria which is what I would like to do. Would you reccomend my upgrading to a 20 high or a 29? The light fixture is 20 in. long. Do you think I could get away with hanging it bove the tank and having 5 in of space on each side? I will have a lot of time to make these changes if necessary because I turned my tibia and fibula into a banana last night at bball practice :(

If a larger tank is possible, you can keep the Rosy Tetras and add to them when you have the larger tank. A group of 5-6 would be nice in a 29g. If you stay with the 10g, perhaps the fish store will take them in exchange; some will. If you do upgrade tanks, get the largest you can manage--meaning, that you have space for and can afford. The larger the tank, the more stable the water--and of course the more fishies.

The watt per gallon is only a guide, and it works for regular fluorescent tubes over tanks that are around 30g and larger. On small tanks it is difficult to get less lighting. Hanging the light fixture above the tank is an option, but I personally don't like this because you then have the glare of the light when you sit to view the tank. I would stay with what you have and be prepared to have it on for less duration.

Sorry to hear of your sports inuries; hope you mend soon.

So with the 3 wpg is 8 hours a day fine? It's on the same timer as my reef tank so I could turn it down to 7 if necessary. 8 is a little too much for a reef so it wouldn't be a problem. Thanks again Byron. Have you ever kept a reef before?

Try the 8 hours, and if algae starts getting out of hand (remember, a bit of algae is natural and not an issue), be prepared to reduce the duration by one hour. As long as the plants are plenty, and nutrients are added, it may be fine.

I'm strictly freshwater.

Do you mind me asking why? I think freshwater is equally as beautiful as salt. But the thing I don't like about reefs if the super negative impact they have the actual reefs in the ocean. This oil spill is really going to mess up the Florida keys a lot. They are already finding huge tar balls in the keys already. On craigslist in my town there is a free 60 gallon tank. If I added all of my freshwater stuff into it and another 50 gallons would there be a cycle? Kind of a stupid question but I'm not sure.

I am not that keen on marine fish. When I visit the Vancouver Aquarium, which I frequently do, I almost never even go into the tropical saltwater section, but I spend hours in the freshwater area especially the walk-through Amazon gallery. I just find freshwater aquascapes interesting and beautiful.

When setting up a new tank, if you plant it reasonably heavily from the start, you can add fish and there will be no cycle. I have set up dozens of aquaria this way and never had ammonia or nitrite above zero. The plants grab the ammonia/ammonium even before the bacteria can get it, so in a well-planted tank the level of nitrifying bacteria is very low compared to non-planted tanks. I explain this in more detail in Part 2 of the series at the head of this section, here's a direct link: http://www.tropicalfishkeeping.com/a...um-part-34859/

Without plants, you can jump-start the cycling by "seeding" which means adding substrate, filter media, wood, rocks etc. from an established aquarium. The nitrification bacteria colonize all surfaces under water, so moving any of these items is transferring bacteria, and provided there is a source of ammonia in the new tank the bacteria will use it and live.
