They do it a lot. It can mean they are just getting to know each other or, as stated, males seeing whose boss. What sex are they?

You can use tape or, if the tank is close enough to the wall just sit the poly behind it. If it is for under the tank of course, no attaching is required.

I am against adding anything to a tank if it isn't necessary.

The daphnia clear green water but they must be able to do so before the fish eat the daphnia

I imagine the Waikato Club would be closest. I am a little vague as to the exact location of Taumaranui (apart from knowing it is 'on the main trunk line' ) although I have visited relations there.

The planaria are harmless so just cut back the feeding and vacuum thoroughly when you do a water change and it will fix itself.

Have PMd you.

and has something been changed recently? More or less fish? New food? Done a water change?

Since I have external canisters I am sorry I can't recommend a suitable pump except to say buy the biggest you can afford.

I too am worried about how she is cleaning the tank and agree with the others, the tank is way too small for a shark or angels. That fluff is fungus, which is a secondary infection usually from a wound, as noted. It may have got in a fight with another fish, damaged itself on decor, or been sucked on by the "sucker fish" depending on what it is. Can we get a pic of the sucker as well?

I get a wallpaper scraper from the $2 Shop. They are wide and have a large blade.

Marlborough's Anniversary Day today Erythromycin is a prescription only medication. What are you needing it for? I have a source 8)

I am not at work so can't check but I think Maracyn is Erythromycin isn't it?

I think it is only male oscars that would go blind and get hairy fins

Great name, I love it :lol:

Although I am a fan of UGF in small tanks, I feel a 250L needs more, like an external canister filter.

I assure you it isn't finished Gotta take more once the pond plants have been added and all have grown heaps.

White cloudiness may be a bacterial bloom caused by the water change. It is harmless and should clear in a few days.

You are right Zev but we haven't got around to it yet.

Nah, just drunk again :lol: Neither she nor her baby duck can swim upright :roll:

OK, here's an update of the pond. Remember the start? Then April... and now October... The water itself is actually clear but with no plants for competition, the algae growing on the bottom shows up clearly. The water lilies are just starting to throw up new leaves and I have planted pots of Japanese irises around the edge.

I don't know about knifefish sensitivity but I would remove the krib and treat her separately. Cheaper too if you put her in a small treatment tank as you use less meds.

Have you got a pic of it? I have seen actual box filters that are round balls and it may be one of these rather than an airstone.
