Just went for a visit to the LFS to see the plants and I'm quite pleased! They have a good range (he showed me all the ones that don't need fertiliser as a priority). I have decided to go to the world of CO2 as well, as they have liquid CO2 available (about 100ml for only 3.50 (I assumed that's good). The shop doesn't have Pygmy cories, so I won't be getting those on Monday, however the man that runs my LFS has a shop in Malvern where he has Pygmy Corys, and so I'll get those on a later date. On the bright side they have harlequin Rasboras (about 11 of them, hopefully at least seven of them are left after the weekend). I completely forgot to look for a whiptail catfish lol. Aren't they known as sucker fish too?

There is a big time difference between us, so my responses occur long after you've done something.

Floating plants don't need added CO2. At the surface, they assimilate most of their CO2 from the air, not the water. This is one reason they grow so much better, faster and easier than submersed plants. Some basic liquid fertilizer in the water would help with other nutrients, I recommend Seachem's Flourish Comprehensive Supplement. A small bottle will do you, since you use very little--in your 10g, a 1/4 teaspoon once a week is it. The Brazilian Pennywort is nice floating, but it will root in the substrate too, and you can allow it to grow up to the surface and then over it.

If you haven't opened the carbon bottle, can you return it for credit? Maybe for the Flourish Comprehensive? I'm assuming the carbon is Flourish Excel, or something similar. Even with submersed plants, I am not a fan of these. Won't bog down this post with the reasons now.

Light. What type of tank light fixture is it, an incandescent (screw-in bulbs) or fluorescent (tube)? I'll assume incandescent, so go to a hardware-type store and get a package of daylight compact fluorescent bulbs, 10 watts. GE, Sylvania, Phillips make these, Westinghouse too I think. Look for compact fluorescent in 10 watts, then make sure you get "Daylight" with a rating of 6500K (K stands for kelvin). |Two of these will be good. And on for probably 8-10 hours max per day. When you're normally home to view the tank. A lamp timer from the hardware store is useful to have a consistent light/dark period. Check out this on light:

Pygmy Cory is a delicate Cory, in my experience. They easily succumb to water issues and I would only add them after the tank is well established. What other corys do they have?

On the feeding, one tablet/pellet/disk should be sufficient. If the disks and pellets are small, two. If it is the shrimp pellets, 3-4.

Hey byron,

I haven't bought anything yet, I just passed through :D

As for lighting I have fluorescent tubes, don't know what K they are though.

With the plants, the bloke at the LFS says that I can put some plants in with the substrate with no fertiliser. He sells them with soil in these plastic tabs (by soil I mean a kind of fertiliser and tab a kind of plastic bottle that's quite small, like a lid). Can I have those as well as floating plants? He showed me a few that can be with any type of light brightness or K too, the ones on display in the shop were in a similar gravel type to mine (different colour obviously lol) and didn't have any fertiliser, just the tabs.

As with Corys, I think I recall one Cory that's name was something like black Cory. (I could be mixing it up with another label, does that name ring any bells?).

Never heard of a black Cory; but common names are often "common" only to those who use them or to that locale. With well over 100 species of Cory and more being discovered annually...? If you could find a photo I might pin it down.

Substrate: plants will grow in any substrate, be it plain sand, plain gravel, an enriched substrate or soil. And equally well. The light however is critical; some plants may do OK under your light, some may not. Spectrum is important to plants, plus there is the appearance to us (colour rendition of fish and plants). What is printed on the end of the tube you have?

If you can get names of the plants I or others can offer advice on how well they should do with what you have. Not all plants are the same, but many are quite adaptable to light. As you don't have it, avoid the carbon stuff. I didn't go into this previously, but using a carbon supplement raises the necessary level of light and other nutrients to balance, or it will not be beneficial and can cause terrible algae issues. Carbon occurs naturally as CO2 and if you can balance that [every tank is different] with adequate light (intensity and duration) and other nutrients are available, plants will be thriving.

Hey Byron,

So I was looking back at this thread and forgot about the possible trio of corys that I could get. What would be best for my tank size along with the 1 Bristlenose pleco (I assume that the 8 Harlequin rasbora don't affect how catfish will feel).

As you said before pygmy's will be difficult due to them being more easy to disturb with water "difficulties", so what types of Corys would you recommend to me? I was hoping for ones that like to school and have a nice character too, and those that of course will get along with the bristlenose pleco my only current substrate fish. Who by the way I'm in love with haha.

I'm going to pop into my LFS tomorrow and make a list of all the Corys that they have. That will probably make it easier to determine what I can get. (That depends of course on whether or not I can get 3 more fish into my tank without becoming overstocked, what's your opinion on that?).

The usual corys are very adaptable. Imported wild caught would need close attention to their water. The 3 dwarf species I have always found more difficult. Let me know what they have; there are many species in our profiles. Fluctuating water conditions (thinking here of temp, ammonia/nitrite/nitrate, pH) are not handled well by corys, but that should not be an issue in a planted tank with regular water changes as there will be stability.

The LFS stocks plants and fish to sell in most cases. They are not in thier tanks long enough to require needing fertilizer or in the case of the fish the right size tank. Again depending on the plant or fish. I have also learned not to take the the word of the local fish store as gospel. Do your research and continue to ask questions prior to the purchase. You and your fish/plants will be much happier.

Right, after my visit to the LFS I only found they have two types of Cory, one was labeled green/brown Cory and the other was labeled Skunk Cory. Are these two good for my tank?? Skunk was my favourite

The green/brown is likely Corydoras aeneus, it is the most widely seen cory. Check the profile [click the shaded name], info plus photo there.

The skunk is probably Corydoras arcuatus [photo below]. I just noticed I have not added this species to our profiles yet. It is very similar to the so-called Bandit Cory, C. metae, and the David Sands Cory, C. davidsandsi, and the False Bandit Cory, C. melini. Common names are usually made up by the store or supplier, so it is possible to see any of these species under any of the common names. Those in our profiles, and all of these except C. arcuatus are, have photos.

Either of these will manage fine in your tank.
