loss of colour in loach

[rhonda]

1 of my loaches faded. I have notes this a few times but then they get there colour back this time he was very pail. He has been in an 8 foot tank for a few weeks as a companion for fronnies, yesterday he was flittering around as usual, and he was eating and looked happy apart from his colour. the water is excellent , I keep a close eye on all my water .I know fish die put this morning he was dead is there something I should be watching fore

what substrate and pH were you keeping ?
africans like your frontosa normally require a higher pH and harder water where as asians like the clown loaches prefer lower or neutral pH and softer water.
