do you think I can add 6 neon tetras to the aquarium? I do 50% water changes daily. I still dont see any leaves :(

I have empty ones I'm not allowed to fill here... They just state, "No dogs or cats - caged maybe OK". So I'm gonna go with anything I can keep in a cage I can have. Hopefully there will be trees nearby to maul for my caterpillars. Roommate is getting a tarantula, I forgot what we are gonna be calling it. I feel like I should get snake if I have room/time. I said I should get a bunny, but apparently thats the one thing my friend is allergic to. Sucks cuz I learned some amazing stuff about bunnies today.

Yeah eels are friendly, their current tankmates are much too robust it seems for a planted tank. Stick with the tetras because they have a smaller bioload so they fill the tank better w/ more fish. Angels and rainbows have taken to munching my stargrass. I'm keeping a few of the bows for breeding, never intended to keep all 11ish of them though.
do you think I can add 6 neon tetras? Im glad that you can take your tanks it will be a crowded room but you would have much company caterpillars? what kind? do you like tarantulas? I saw a very beautiful colombian boa snake in petco and there was an iguana also for 20 dollars and I thought that was really cheap because iguanas get like 3 feet! what amazing things about bunnies did you learn?

I judged your stocking based on 8 danios, which i assumed all 8 were the common zebra danios. These fish like space, swim in the middle and grow to about 2inches. Since you change water 50% daily, pollution is not much of an issue, but danios are all mid-top fish, and are very active swimmers. Again, assuming you have a standard 20gal, the amount of horizontal swimming space is just about adequate. Now i said close to stock because zebra danios are mostly mid level fish so adding bottom feeders or surface fish will not affect them as much.

Seeing as how neons generally hang out from mid to lower regions of tanks, I would say 6 neons are fine. I would even venture to say you can have 8 or even 10 neons.

As for your crypt, i once replanted a crypt in 2 places within 2 weeks causing it to melt twice and it just never came back the second time. I think part of it is how much nutrients are left in the rhizome for the plant to return. The melt probably (im not an expert) uses a lot of energy to bring the plant back so moving it too much might cause it to not have enough to restart. How long has it been since you moved the plant and the melt?

oh really?? its a long tank so thats good right?? do you know how long they take to get full size? my little ones are barely growing Im kind of worried. Do you have neons or have you had them in the past? I hear they are kind of mean do you know if this is true?

really never?? the funny thing is is that the one that I broke into sections that one only melted a little bit but the other one that I didnt even touch only has a few leaves
back when they were fine I just believed they were the most beautiful plants in the aquarium I mean they were blooming and big and healthy! Im pretty sure that the reason they melted was because I added a whole cap of flourish comprehensive and when I did the water change the water was colder than normal.

Long tanks are always better for characins, rasbora, danio. SinCrisis was quite correct. Those that like to swim need the length, but even beyond this there is more surface area and that is good for the gaseous exchange (even with plants). A larger surface are allows you more fish than a taller tank, even within the same volume. Within reason of course.

Neons are shoaling fish, and all shoaling fish need a group. The more the better. Neon Tetra are quite peaceful fish--but keeping them in too small a group (less than 5-6) can cause aggression. This applies to almost all shoaling fish. A recent scientific study looking into this concluded that all fish tested showed increased aggression when maintained in less than 5 per group. Many of us have been saying this for years, but it is nice to now have scientific evidence.

Remember your water temp when selecting fish. Neons do best in cooler than average water, no higher than 76-77. Danio are fine with this too. But if you were to consider some fish that need warmer temperatures, you would have problems. Our profiles give optimum temperatures for each species.

When i had danios it took them around a year to get from approximately 1 inch to 2 inches. I had kept albino ones. For neons, i used to have them when i had a 20g tank, kept ~10 of them with a pleco (yes i know the tank was too small! i was young and uneducated). They were great, i never really saw aggression, but with a group of 10 it probably fizzled out.

I do have vicious tetras right now, black skirts that i have are very very aggressive, most likely because there is only 2 now instead of the 6 that were there 4 years ago. Been trying to net them and donate them but they're super fast. If your looking for peaceful, do not get black skirts, ever.

In a 20 long you could probably get some awesome rasbora schools, like the mosquito rasbora, super small and i hear they school very tightly (cant find them here so i dont actually know). They stay mid to low as well.

oh great thats good to hear! I will probably be getting 6 neons when the aquarium gets more dense with plants. Then I will add 2 more after a week The Danios are so lovely and peaceful I really enjoy watching them they are such lovely animals they really are.

The neons will be the only fish that will be added to the tank after that it will be all about giving them a happy healthy life

wow a year? I still have one little baby and he's been tiny for like a month now! I think the others have grown a bit but not too sure.

those mosquito rasboras are very pretty! I'll see what the store has to offer I cant wait to add more residents to the aquarium!

Just remember to research any fish they may have to offer before you buy them. You want a healthy community, and that means fish species must share common requirements.

For instance, with danio I would not get the Boraras rasbora; they are much too small and the constant swimming activity of danio would be detrimental. These two fish species are a good example of fish that do not go well together.

Many aquarists make the mistake of buying something that looks nice in the store, only to find out later they have trouble. We all learn. But it is better to learn befoere you have fish on your hands that have to be returned or something.
