Here's a pic of one'a my other hobbies; fish keeping. This is my 55 gallon goldfish tank. There are 2 lionheads, one black moor, one white telescope, one true albino telescope, two calico orandas and three babies from when the lionheads spawned last year. And one albino cory cat. And a healthy supply of snails.
I know that some may scoff and call it overcrowded, but I don't care; I have had the thing running for over 3 years (in one form or another; started with a 20g then a 30g, then this size last year.) Same filters, gravel, plants. I have three high power filtters on here that have been constantly running since 2002! Whisper filters all tha way, baby.
I also swear by regular water changes; I take half the water out, once a week, religiously. And add salt everytime I add new water. It works like a charm!!
Enjoy...
