Cant breed them only got 1 tank and have corys and amano shrimp in it so the chances are low that I'll get fry
its a shame cos I luv my killi's there always so nosey and come to the front as soon as I look in the tank plus the male look like he has a constant smile with his markings

all you need for hatching the fry are a could small tubs of plastic. and them you could put them in a breeder net... I guess the chances are low though.

Very lovely aquascape, nice looking plants and fish.

I would stay with that tube [is it one, or two?]. I know what MyLittlePleco is thinking, but the spectrum of the tube is the important thing, and while tubes around 6500K usually have adequate spectrum, not always. And I've had 11,000K tubes with good results. If the plants are responding well, fine.

Hi Byron,
Ive got two tubes but if its a bright day i tend to just have one on due to the tank being near a window which is south facing so has the sun all day.
The tanks not in direct sunlight but the room is alot brighter when the suns out

I do have a couple of red plants (name unknown) which seam to struggle but are still growing,
it's just my gourami's seam to like the leaves for there bubble nests

@Byron This is interesting. I always thought the rule of thumb was 6,500k lighting for planted tanks. Funnily enough I've got two 10,000k flourescents which came with the aquarium and haven't been used. Perhaps I'll switch over to one of them for a month or so and see how plant growth is affected.

@Skerry I cannot identify your red plant, but generally speaking, red plants require very high light. There are a few red ones which will grow in low or medium light, but I'm pretty sure the majority of them need very high light to survive. Could you perhaps upload a close-up of your red plant? I'm sure that will help with identification.

I don't have the spectrum for your fluorescent tubes, but the Kelvin indicates high in blue. If the red is not adequate (and only the spectrum graph for the tube will show us this) any red-leaf plants will struggle. Aquatic plants need mainly red and then blue to photosynthesize, and red-leaf plants need more red or brighter intensity to make up for the lost red wavelengths they reflect. In order to have red leaves of course. If you can provide the spectrum graph, or a link to where I can see it... ?

The spectrum of the tube/bulb is the important thing to know, as that indicates the "highs" in wavelengths emitted by the tube/bulb. The Kelvin rating is the colour temperature, as we perceive it. The two may or may not be related.

Diana Walstad says she will select any tube with a K between 5,000K and 7,000K, or a CRI of 80-100, either or both. But without knowing the spectrum, it is not possible to know if the tube is adequate in red and then blue. When I reference daylight tubes with a 6500K I name the brands, because I know from checking that the spectrum is good. I check the spectrum graph from the manufacturer.

As for your 10,000K tubes, I would suspect they are inadequate. I have purchased new light fixtures for five of my tanks during the past year, and in every case the tubes that came with them were garbage and went straight to recycling; manufacturers were All Glass Aquariums, Perfecto and Aqueon. They were supposedly "plant growth" tubes, but they are like the Aqua-Glo and Flora-Gro series, high in red and blue to give a purplish hue, but very weak in intensity compared to the full spectrum/daylight tubes. About half the intensity, which makes a big difference.

I had a Lightning Rod (brand) 11,000K Ultra Daylight tube over my 115g previously, and it was good. High in blue colour (the K) for a "cool" white, but the spectrum graph shows good peaks in the red, blue (very) and green, which is your tri-phosphor business, and very good plant light. I can't find these tubes any longer locally. The photos of my 115g under "Aquariums" below my name have this lighting combo, one of these plus a Life-Glo 2. The tubes have worn out (lost intensity) and I have replaced them, but not having the Lightning Rod I've used Phillips Daylight Deluxe which is good but I've lost the "coolness" of the LR.
