Ok how bout this stocking plan?

[Jared Learn]

I have a 20 gallon long.

GH- 9dh
KH- 3dh
ph- 7.8

I have a dwarf gourami, tank is completely cycled nitrites 0 ammonia 0 nitrates 10 parts per million. Based on earlier recommendations by some of the folks on this site I was thinking of adding 10 harlequin rasboras and six Panda Cory's. All the fish I have chosen are within the correct parameters according to seriously fish as far as temperature hardness and all that. Please let me know what you think any recommendations. Thanks a million.

And also just out of curiosity would I be able to do some Otto's or would I be pretty much fully stocked with the rasboras cories and the one gourami?

I have no idea how big a 20 gallon long is. But the water appears to be suitable for the fish you mentioned, so as long as there is sufficient room, they should be fine together.

Don't add Otocinclus. You could add some shrimp if you have lots of plants in the tank. Gouramis like surface/ floating plants and Water Sprite (Ceratopteris thalictroides/ cornuta) is a great plant for them. It grows rapidly on the surface but also grows in the substrate.

It's basically 30 in Long 12in wide 12in tall.

The tank is borderline for the Cories but 6 of them should be ok with the other fish in a 30 inch tank.

I would add a few more panda cories; this is a small sized cory, and they are very social, my group of seven are always out and about in pairs, trios, or more. In your tank (I have a couple tanks with the same base dimensions) a grop of 8-9 panda cories would be best. They enjoy swimming in the filter flow, so make sure this is at one end of the tank.

I would not get otos now, wait until things settle and mature if then.

Ok that sounds good, that's what I'll do. Thanks again all!
