20 gallon long stocking

Let me guess who told you that......... your LPS ? Whose goal is to sell and sell again ?
No. Multiple experienced people on multiple fish forums. My LPS does not even have Plecos. I have heard from people that they are OK with plenty of maintenance and that they are not because of their high bioload.
 
So 3 Honeys, 1 BN, and 8 Harlequins will bo good? Might add some amano shrimp as well for cleaning.
Yes, that would be good!


BN in 20 gallon ?? Not at all. not only do they get big but they also get bad-tempered as they get older.
BNP’s (bristle nose plecos) typically only get to be about 5 inches long.

They can be kept in a 20g, assuming you keep up with tank maintenance.


I have heard both. What are the pros and cons?
I have one in my 20g long right now, he is doing perfect. He was in my 29g tank, but I removed him and added him to my 20g long.

I had a conversation with @Byron about it, and he said the stock mentioned in post #36 is adequate for a 20g long.

I assume Byron knows what he is talking about considering that you both have 14,000+ posts! So i should be good?

Be careful taking comments out of context and applying them to other scenarios. But here, as I have read through this thread, I see no issues.

But in addition to numbers in relation to tank volume, which is as far as some people seem to go, you just have to realize that there are other factors equally if not more significant. The number of fish of one species needed if it is a shoaling species (like rasboras and cories are), then how the species interact, where the species spend most of their time inn the water column, whether floating plants/substrate plants are included or not, and the schedule of water changes. The aquascape must provide any hardscape the fish (all of them) expect and need, like wood for a BN to graze, sand for cories, etc.

When all of this has been addressed and provided, the impact of the fish on the biological system will not be as significant as otherwise it might.

I am planning on using frogbit as a floater and plenty of other plants. So 3 honeys, 8 harlequins, and a BN is not too much?

With weekly partial water changes of 50-60%, and not feeding more than necessary, no problems. The cautions not only ensure a stable chemistry, they also give you some cushion, in case you should have to miss a W/C day, or something.

Sounds good! Thanks for the advice
 
So after thibking about my harder water, I was considering 6-8 praecox rainbows and 1 BN pleco. I know the rainbows are good but is the pleco ok in pretty hard water? Once again, sorry for no exact parameters. :(
 
Im also thinking 8 tiger barbs and 6 albino corydoras. Will the barbs be too nippy?
Yes. Do not put TB's into this tank. IMO, they need to be in a species-only tank, in large numbers, to spread their aggression....a 20L won't work, especially with other fish
