i do like having a big community tank, when i get my house i will be keeping a couple of cumminty tanks here and there in the house and i will also have a whole room just for tanks so i can start breeding and selling fish too.
I've had a community tank before... not properly set up though so I didn't enjoy it for too long...
Started out with 4 guppies when I was 5, mom killed them by leaving their decoration in soap and then putting it back in the tank... -.- it was a very tiny tank.
Then at the age of 7 I received my first community tank from a friend. The amount of fish I had in there... X_X was surely too much for a mere 40 or 50L whatever it was... And a lot have died along the years, either due to no filtration or due to dad overfeeding when I left him to take care of the fish.
The community included:
Several zebra danios
A bunch of swordtails (probably 5 or 6, with more females than males)
4 bettas (in pairs)
1 giant betta
bunch of guppies
4 baby angelfish
a bunch of neon Tetra
some kind of golden Tetras with a black spot near their tail
one black molly baby
one dark-red wagtail platy
2 hoplos that my dad bought.
After a lot of them died by 2003, I've ended up with 2 hoplos (not the same I started with back in 1997), 1 male swordtail, 2 male guppies - descendants of my first ones, 1 fantail goldfish and a small Crucian carp I've saved from becoming dinner.
Then in 2005, after a few deaths, my setup went like this,in that same 40-50L:
1 Crucian carp, 2 hoplos (same ones from 2002-2003), 2 silver fantail fish, 1 black moor and 2 male swordtails (dad bought the other male when it looked like a female...)
Had them for several years until 2009 when I lost the fantails/moor, both swordtails and the carp. Then in 2010 I lost one of the hoplos.
Now I have 1 of the hoplos from 2003 left, a pair of adult swordtails and 2 swordie fry. But a 76L tank, a filter, a heater, sand and a plant that started to spread. It took me 17 years to find out about cycling a tank. X_X
