i have just been given 2 tanks from my friend who was moving, 1 is cold water and ive started a thread in there for that one,the other one is tropical, it is 3ft x 1ft x 15 inches, and it has 1 kissing gourami, which is now 9-10 years old, 2 silver dollars and 4 albino corys in there, when i first saw the tank i couldnt believe anything was alive in there, the filter was so clogged it was trickling out, it is a fluval 4+, ive cleaned it out in old tank water, and have had to swap the media in it, so i just did one side first,and will change the other side asap. the gravel in the bottom of the tank was thick with scum and dead fish, (she said the last time she looked properly she had 4 neons, 3 leopard danios and 4 zebra danios with all the others,i found the rotting bodies of 1 neon and 1 bigger fish under a rock thing),so much so that it was like a mix of slime and stone, and i couldnt stand the smell,so ive changed the gravel to black sand, the corys seem much happier now, and im doing regular water checks as im expecting a cycle now. i cannot buy a bigger tank as i have no room for one, and the stand it is on is 4ft on the top (has 4ft tank with fantails in)and about 3.5ft underneath,so i cant really put a bigger tank under the big tank anyway. im hoping since hes been in this tank now for some time hes ok in there,especially without the dead fishies in there,and the half handful of food she put in 3 times a day,she said she has had him for all his life, and when she first got him he was a tiny fish,and hes grown to well over 6inches now,she did have 2 but this one killed the other one. so now the kissing gourami has 2 silver dollars for company instead of another gourami. all seem happy, swimming well, eating well, and i just wanted to check what peoples opinions were of keeping these fish in this tank. i cant believe people get away with such awful neglect just because they are fish :mad2: at least they will be properly cared for with me,i wont ever let them get into that state again.
