Depends on the fish. A betta or other small anabantid could be fine. The duckweed will suck up nitrate, but will also interfere with the diffusion of oxygen at the surface since it will eventually cover it all. A small waterfall and/or regular thinning will help avoid low O2 levels. A mass...

Adding CO2 to an aquarium is for the plants.

Try filling the container with hot tap water and then peeling the sticker off. Works pretty well for most labels I've done as long as you don't overflow and get the sticker too wet.

Well, you said that it was "Not symbiosis. However it is commensal". Commensalism is symbiosis. A common misconception is that symbiosis = mutualism and your reply would actually have made sense in that regard if you meant to say mutualism instead of symbiosis. The article states that the...

Commensalism is a type of symbiosis. Symbiosis is a general term that covers a close relationship between organisms. The argument here would be is it commensalism or mutualism (not all symbiosis is mutualism which is what your statement suggests). It boils down to whether or not one or both...

Running 2 lamps on that tank is quite a bit of light. I run one light each on all 3 of mine that size and they are heavily planted. Running 2 would put out too much heat and light IMO. Sent from my iPhone using Tapatalk

I would err on the side of caution and go with a plain old CF bulb of 13w or less. It has not been shown that tree frogs need UVB and could cause problems in those tight quarters. I did a lot of research before getting bulbs and decided to use 6700k 13w CF bulbs in my 12x12x18 gray tree frog...

If you are careful, you should be able to peel it off with little to no damage to the ootheca. Sent from my iPad using Tapatalk - now Free

I wouldn't bother with supplemental heating unless the room was below sixty. I've had no problems with keeping mine at school where the temperature can drop into the low to mid sixties during winter and not get above the low seventies until late spring. They still eat, molt, and move about...

You actually use an actinic blue light to enhance the colors just as you would for saltwater fish and invertebrates. Black lights can harm their eyes and long term exposure isn't good for scorpions either.

They are a transgenic species with inserted DNA from another species that results in the fish producing a protein that results in their new coloration with fluorescent properties. Crossbreeding is totally different and involves the crossing of different breeds of the same species (think...

Grammostola species are pretty good classroom display specimens IMO. Rosehair, Chaco, or Brazilian black are all pretty laid back (not big on flicking hairs), predictable, out a lot, and hardy. Geniculata and LP are more feisty and tend to flick hairs, but not as bad as Brachypelmas (curly...

The current use of inserting a gene that causes an organism to produce a fluorescent protein (they don't actually glow) is not harmful to the organism. There is much more precision in genetic engineering and unlike selective breeding or hybridization, less chance of unwanted genetic side...

If it was gene therapy to treat or cure a disease such as cystic fibrosis, diabetes, cancer, or any one of the myriad of debilitating genetic disorders then...yes. As with any technology, it is the way you use it. You are letting your personal bias dictate the value of this technology without...

I'm not sure that you have a case. By your own logic, the majority of plants and animals we use every day are "sick" and were created by "monsters". Selective breeding of plants and animals is not "natural" and humans have done it since our early beginnings to serve our needs. Transgenic...

We are all a mix of genetics. I would actually consider them the opposite of mutts due to the fact they are from limited breeding stock and that can cause "sick" fish. It is a lot cheaper to breed existing glofish than to genetically engineer new ones.

Glofish don't suffer...they haven't been injected with latex or dye. Their body produces the protein that results in their color. It is in their DNA. It is similar to selective breeding that humans have done for millennia, only more focused and precise. The same technology used to "create"...

Remove the males as they mature into a separate container or feed them off. My colony breeds at room temperature.

As long as you are keeping your T's on dry sub with a waterdish, you are good to go. If you get the sub too damp it might fog up and mold, but it can be done. I've been keeping several adult T's (and 1 Emp) in the men's sized containers with no issues for a couple of years with the stock...

It is my understanding that floral foam is toxic. It contains formaldehyde among other things. I would not recommend using it for any purpose.
