I have never had a problem with aggressive males. Are you able to increase the number? This should help. They are a shoaling fish so the more you have the better behaved they will be.
ChCh is ideal for fish keeping generally.
pH is altered by driftwood and peat (lowers), fish (bigger fish will tend to lower pH) and some rocks, like limestone, and shells (raise pH).
Eventual adult size is mostly determined by how much they were fed as they were growing. If the fry were not fed enough it will permanently make them smaller, not matter what they eat as adults.
I think some of the fancier goldfish can be permanently damaged and always have trouble swimming up the right way. Since the fish was otherwise healthy and was not in pain (as far as anyone could tell) the owner decided the cork was a compromise - and it worked.
Not sure when those fish started to be called lambchop rasboras. They look like Hengeli rasboras to me. A beautiful fish. Like a small, more colourful, harlequin.
We have 5 vehicles - they just won't fit in the garage. One of the MX5's does now though
I must say the reaction from the inspector was odd and I would be querying his boss.
We have several hundred temporary vineyard workers here at the moment. You walk the streets and hear all sorts of different languages. Very interesting.
Visited the cops at lunchtime and they think it should be fine as the keys were handed in pretty promptly. They think it was "grab any cash and run" without further thought. Hope they're right!!
I couldn't run mine that long as it blocked. Lots of plant matter and barbs :roll:
(meaning the barbs nibbled the plant matter, not that the barbs, too, blocked the filter :lol: )
