New Tank Questions!!
I had a 5 gallon tank a couple years ago, but now I would love to get back into the "fish business." Right now I would like a 3 gallon tank that I can plant live plants in. The aquarium I am looking at is the Aqueon Evolve 4 which is about 3.2 gallons. In this tank, I'd like to have a school of 3, possibly 4, Rasbora Heteromorpha Danio. The plants I am thinking about are: . Is that led light enough for these plants? The substrate I would like to have is a layer of CaribSea® FloraMax™ Planted Aquarium Substrate and then a thin layer of rocks or pebbles on top of that. How does that substrate sound?

Now, I plan on doing a fishless cycle. I have pure ammonia. Here's my plan: 2 drops of ammonia daily until NO2 peak, then one drop daily (until nitrites 0 or until im ready to put fish in?). How does that all sound? Also I have a question about raising the temperature. Is it safe for the plants if I raise the temperature to around 85 degrees f. to speed up the cycle? Will this harm them?

How does this all sound? Anymore feedback or comments are welcome!!

Thank you!:-)

First off, welcome to Tropical Fish Keeping forum.:-D

I am not absolutely certain what fish you have named, the link does not work, but I will assume the fish to be the Harlequin Rasbora, Trigonostigma heteromorpha. You can click the shaded name to see the profile with photos. If this is the species, it needs a larger group, no less than 6 but 8 or more is better, and that means a much larger tank space, no less than a 24-inch tank such as a 15g or 20g.

As for the cylcing, if live plants are intended you willnot need to do any "cycle" as the plants will do it for you. They assimilate ammonia as their preferred source of nitrogen. The temperature question is not relevant now, but for the record, a temp of 85F is very warm and this would likely affect some plants and fish long-term.

Thanks Byron for deleting that other post with the questions:) I had heard that you could keep those fish in a group of 3 or more, but if it's not going to be good for the fish, then I will find another species! How about one beta fish? Is there any other option or is that the only species?

Say I did have just one beta fish could I put some shrimp in there or a otocinclus? So the plants would easily be able to take care of the ammonia because of the low number of fish in the tank? Also, what if I set the tank up a day or so before I get the fish, should I put a drop of ammonia in there to keep the plants happy?

Thanks again Byron!

Never add ammonia when there are fish in the tank. Your fish is the ammonia source.
Are you cycling the tank or will it be heavily planted?
Otos are a no go because you need at least 3 of them.
As far as I'm concerned, a betta will be the only thing that'll fit in your tank. You can have some shrimp as well, I recommend amano, smaller shrimp have a chance of being eaten, some betta will eat them, some won't. I recommend going to the betta section of this forum, we have lots of care guides and such for them. :)

Thanks Olympia! I meant that I would put ammonia into the tank to feed the plants until I got my beta or whatever fish/shrimp I got. Yes, it will be fully planted with Dwarf Baby Tears, driftwood, Dwarf Hairgrass, and some taller plant for the back! Do you think those plants can take care of one or two fish?

What about a mystery snail? Would ghost shrimp be ok with the beta? And how many? Or what about 1 dwarf gourami? I've researched that they only get to about 2"? (my tank is 3.2 gallons).

A mystery snail might be a little too much bioload wise. You might be able to do a single rabbit snail if you can find one for sale. :)
Ghost shrimp should do great.
Dwarf gourami are small, but very active and like large tanks.
A betta really is the only fish option in such a limited space.

Well, I will cross the mystery snail off my list. I am kind of stuck between a betta and dwarf gourami (i know that the gourami might be pushing it a bit, like you said olympia :) ). I don't reallly get excited when I hear the word "beta" because everyone has them and it just seems like they are kind of boring. Then the dwarf gourami seems really interested and is small..... I think I will just set up my tank and put ammonia in it until I can figure out the fish I want:)

If you don't mind paying a high price- has stunning betta.
Before dwarf gourami, I'd recommend dwarf puffer, 3 gallons is a tad small, but for a single puffer it could work out.
Good luck with the plants!

Well, I researched some more and I think that I will get a male betta and some ghost shrimp. How many shrimp can I get? Will they multiply fast and if so how do I keep them from overcrowding my tank?

Or, what if I did 4 or 5 cardinal tetras? Or would that be too many?
