Add more fish?

JohnnyD44

Hey Everyone, I currently have a 20G Long tank, I wanna add some more fish, possibly some bottom feeders if I could, anything really....Here are my specs right now:

2 Silver Sailfin Mollys
3 black skirt tetras
6 lemon tetras
1 small Silver Dollar fish
1 bosemian rainbow
1 honey guarami (sp?)

I possibly thinking another school of tetras, or some bottom feeds

any and all advice is welcome!

thanks!

That is a pretty full tank. What about replacing the Silver Dollar and the rainbow with some cory. Both fish get a little large for a 20g. Rainbows are alot happier and show better color in groups. A 20 would be to small for a group of them.

Yh i agree that tank is pretty full if u need rid of food on the bottom of tanks try investing in some algae eaters (snails) but if u do u need to take into account they do breed alot

I would not get a snail expecting it to clean your substrate. That is what gravel vacs are for.

I think he just wants something new to look at.

not all snails breed alot infact i believe some species wont at all in the home aquarium. its also true that not all snails are algae eaters. adding snails will just be adding to your bioload.

The Silver Dollar and rainbow are both schooling fish that get too large for your tank. I suggest replacing them with more black skirt tetras, as they will be much happier in a larger school. Then, you could possibly add a couple of mystery snails to help with eating food that ends up on the bottom, but keep in mind these snails will add to your bioload, not take away from it.

Snails that live in FW and breed quickly
Pouch snails (Physas sp.)
Malaysian trumpets (Melania sp.)
Ramshorns (Planorbis sp.)

Snails that live in FW but will not breed as quickly as the top category
Pomacea diffusa
Pomacea canaliculata
Pomacea haustrum
Pomacea insularum
Marisa cornuarietis
Asolene spixi
European nerites

Rate of reproduction of snails above (except nerites) depends on environment. They may still breed quickly but you can easily regulate their population by crushing or freezing the egg clutches laid above waterline. The last two, marisa and asolene lay their eggs in the water so you may need to hunt the eggs although hatch development takes days and even weeks depending on the temperature.

My canas lay an egg clutch daily or every other day but I just crush some egg clutches that I find as I have over 300 of these already.lol

Snails that live in FW but will never breed at all
Nerites from Asian and American countries-They need brackish to marine conditions in order to breed. The velligers (larva) need microalgae or phytoplanktons in order to survive.


The only snails that eat all algae effectively (with the exception of BGA) are nerites.
