how many tetras in a 45 gal corner tank?

[Dynamite fisherman]

here is my question how many tetras can put in a 45 gal tank, i have 4 bleeding hearts, i know the rule of 6 or more but thats all pet store had. and can put more than type together, or is it a bad idea to add differt types together?

How many bleeding hearts for a 45? I would say 20-30 is probably fine depending on dimensions.

Smaller tetras like neons, twice that or so

Adding other species of tetras wont do much for the bleeding hearts, since most often different tetra species wont school. Its important to get 6+ with the BHs since they can be especially nippy/bumpy like a lot of larger tetras.

I say 15-20 depending on the other tankmates. I would stick to the same type in a smaller tank like that.

Might also want to consider the depth the fish you choose like to stay in. Then try to pick other fish that will fill in the other depths in the tank. That way their a nice balance in the top, middle and bottom of the tank.

you could add another 4 bleeding hearts to the school and another robust tetra species say 8-10 pristella,or serpae or red eye - any one of these in a group of 10 would look great with what you have.

I think the answer to the question depends on your filtration and your water changing/tank maintenance schedule.

Really depends on your tank mates too.

Also I f you wanted to have multiple types of tetras like if you got 8 bleeding hearts and 14 neons that would be fine. they do not care in the slightest about other schoolers.

its a 45 pentagon shape, java moss, several apono plants, and soon some horn root, a hob filter that does 245 gph with weekly water changes of 10 to 15%. hopefully will add some ottos and kuhlis and maybe some hatchets, and of course few more bleeding heart tetras and others if possible.

Thats the best way to put it for sure. How much water you change is going to be directed related to how much nitrates are produced. Just test them the first few times to get a feel for how much to change. under 20ppm is good under ten excellent. The plants will use up some nitrates once they are established
