Females tend to be a little deeper and wider in the body, but this is not always readily apparent. As usual, males tend to show a little more colour then females.

The "rule" always was 1" per imperial gallon, a value which I always felt uncomfortable with thinking it tends to over stock. Barbs are clean water fish and a packed tank is not going to do them any favours at all. That said, the quality of filtration gear these days is perhaps better than it...

Schooling is a defense strategy - if your fish do not feel threatened, (which is good), they will not adopt a defensive posture. In a tank that small, schooling would be unusual anyway.

Definitely not to shabby. Not seen them for years. Nice to see.

With young fish of a species as variable as B. kubotai you will be hard pressed to find similar looking examples in different shipments from where they were collected.

I assume you have your reasons for using aragonite and are aware of it's chemical properties. As Rooster says, just shorten the inlets, I also have sand, (swimming pool filter sand), and have no problems. It is true that excessive sand going through a filter will erode the impellor and housing.

... but not well enough! You didn't answer these questions... ... I can now see the type of valve you are talking about so my last question is no longer relevent. It takes pressure to push the water out of the tube in the tank, more if there is some kind of diffuser on the end, that is why...

When you have one valve open is there plenty of flow or just enough to allow the gas to reach the tank? Is the line into the tank open or is there something on the end that would create a back pressure? Are each of the two valves seeing the pressure from the other and backing off? What sort of...

Corner tanks, by virtue of their geometry, are difficult to get a lot of light into using traditional fluorescent lamps. To get value out of CO2 and EI you will need to consider how you are going to get your light.

Moving fish is always stressful, adding thus stressed fish into an environment known to be challenging is not a good idea.

If you click your name above and to the left of a post, there are options to view posts or threads. Is that what you mean?

Moved from DIY?

Technically maybe. It is years since I used an airpump, but when I did, I never had the tube blow off the pump. If it did and the tube had some kind of diffuser on it, then the rate of water ingress into the tube would be so low it would take an age to reach water level. If the tube was open...

For food use, if clean, no issues. Containers for food use are generally made of materials selected not to leach materials into their content. Shrugs shoulders. What kind of art supplies? Water soluable material? Pigments? Metals?

What was in it originally? If it was for food use or similar, it will be fine if clean.

I suppose there are fake flowers and then there are fake flowers! They could be made of anything, and unless you have exactly the same type as your friend, you are starting from scratch. Even if your friend has had them for a few weeks it is no guarantee what will happen long term.

Assuming these are for the 200l tank, yes, no problem, once it is cycled. The various types of Tiger Barb are all the same species, the colour morphs are man made. If you are intending to cycle with those fish, then that is a poor choice. Barbs are very sensitive to Nitrogen pollution and...

Looks like 2 Barbus johorensis and possibly a Hypsibarbus wetmorei as well.

When I want to reduce the impact of spray bars, I drill more holes, make the existing holes bigger, or take the end bung out and add another spray bar on the end, or a combination of all of those things. I usually have the spray bar below the surface and angled so that the water "squirts" down...

What you describe is very characteristic of spawning Harlequins. The females lay small colourless eggs on the underside od leaves and the male wraps around her to fertilise them. Fertile eggs remain largely colourless and hatch, after about 24-30 hours. Unless the water is pretty soft, the eggs...

If the air pump is at a height which is higher then the surface of the water, then water cannot siphon back into it. Having the pump "below the water" means at a height below the level of the water, not actually in the water itself - that would be a bad idea. If the pump is located lower then...

Yes, just cut the airline and install the valve. I will add my usual rider when any subject about airpumps is involved... "unless you have a specific requirement, an airpump is not necessary". Airline cones in numerous sizes, but the "regular" airline for aquaria is standard size. What differs...

Backs and, depending on setting, sides of my tanks get 2-3 coats of blackboard paint, on the outside of course.

Mods can't, but I will post on the mod board if William is around.

As you've probably worked out from the other threads, there have been some server problems in the last few days which hopefully now are fixed. :)

I'd move them all. If they have spawned, the fry from any surviving eggs will be hatching in 24 hours and will be eaten. Female danios, and most Cyprinids let's face it, fatten noticeably in the absence of males and in good conditions. That is somewhat odd. Reports that the fish is "easy"...

When segregated, did the females obviously take weight on? I presume the heavily planted is home to others so attempting a spawning in there is out of the question? It certainly sounds like they're bothered by the surroundings. I'd segregate again, perhaps for a bit longer, 14+days, with a good...

Yup, not enough space for TB's.

Serpæ are notoriously aggressive miniature piranha! I would never keep them again. They should always be kept in larger groups, and even then, not with slow moving fish or anything with long fins. If you have the sapce, both species you mantion should be in groups of 6 ideally more, and in the...

A lot of sealants sold for bathroom and kitchen work does, indeed, contain fungicides which will each into the water with potentially fatal results. Most sealants form DIY shops say whether or not they are suitable for aquarium use.

Any good quality flake food will do. They will be better if that is supplemented with some frozen food from time to time. If your source of live food is safe, (disease and parasite free), they will like that too.

As has been pointed out already. The people here are posting about their experiences when dealing with a particular retailer. They are not, per se, posting bad things about a shop. Enough, you know I mean that.

As usual Rooster, we get to debate semantics whilst basically agreeing. I call lamps "lamps" deliberately. A lamp is a device which emits light, (Dictionary.com). In the business, fluorescent tubes, W filaments, LED's, wick's etc. etc. are different technologies, but they are lamps. The...

Fluorescent lamps that screw or twist into a socket have the starter, (electronic, not a ballast switch), built into the base. It is not in the lamp itself. The end electrodes inside the evacuated tube "boil" metal off which tends to deposit around the end of the tubes. It is this that causes...

Just because the thread is about heaters, there is no need for it to get heated. Keep it tidy.

Not all of the forums have picture upload enabled, it is a band width thing. Either post them in Fish Pictures, or use a picture hosting site like those mentioned above and then use img tags to include them in your posts.

Live feeding is always an emotive subject. On the forums here, live feeding videos, if they have genuine merit are tolerated on the Predators forum. They are routinely removed from other places, and of course, if you had reported the thread, it would probably be gone quite quickly - now I have...

This is not really a CC&A question, but then again, is it NW or OW Cichlids, or Oddballs, (Birchirs!). I'll move it to NW for the sake of the angels and see if you get any further info there!

Neon tetras, even stressed, and man made mucked about with ones, don't have black markings in the caudal peduncle or light markings beneath their non-existant black ones. It is not a Neon Tetra.
