Silver Dollars and dirty water

**Lady Hobbs** · 02-23-2009, 05:34 PM

What is it with these guys. Usually water changes promote spawning with fish but with my Dollars, let the water go without their water change and they spawn like crazy. I don't get it.

They're suppose to not like higher nitrates, as well. I wanted to change their water today but they're having so much fun, I hate to interupt them.
Going strong 6 hours now.

it could have something to do with when they spawn in the wild.
Fresh clean water occurs in the rainy season and also means strong currents,
stagnant water has little or no current to wash eggs away,, maybe?

I totally agree Hobbs, mine do it to! The longer I leave it between water changes, the more they go at it LOL.

Al has a good theory there. I also suspect some environmental factor in their native place, thats the only thing that makes much sense.

Strange, isn't it. Makes me think in this particular fish, they like the higher nitrates. I just stole this info from the internet.

In nature these fish spawn in shallow, sun drenched flooded areas of rivers. In the home aquarium they have been breed in clear aged water with a temperature between 81 and 90f. The eggs hatch in about four days and are free swimming a week later. If well fed they will grow very quickly.

But Wow. I don't keep my temps that high for them. More like about 78 but I'm not looking for a spawn either as I can hardly use 2000 babies. I did put moss in their tank and they are NOT eating it and are laying their eggs in it.

My temp isn't that high either, I've always only had mine about 24C (I think about 75F)

Don't think they are that fussy, I think they just like going at it! LOL

hatch the eggs and give your other fish a treat

My other fish think the eggs are a treat, LOL, you should see them when she's spitting the eggs, out, they follow around behind like it's a big smorgasboard!!!
That's how I know they are at it again sometimes, it's follow the leader round the tank.
