I am the designated Plant Person™ at the shop, and customers will come up and ask about aquatic plants… So I first ask them, ‘What kind of light do you have?’ to get a general idea of what may live in their tank.
I get the vaguest answers anywhere from “it’s a bar light” , “it’s an LED”, to “it’s a light bulb”.
I just tell people that I can’t really help them without knowing their light source but here is some low light plants that may or may not work. They almost always still go for rotala indica and red ludwigia anyway despite my warning, while at the same time saying “our light is brighter than this”.
We have two 48″ Fluval plant LEDs running across the monster +-200g tank. orz
Now I’m not well-versed in light stuff but there is only so much light in the visible spectrum that the human eye is able to see. Blue and Red are near the furthest ends of the spectrum we can see…
Blue light-450-490 nm wavelength light- penetrates water deeper than other colors of the spectrum. Blue is necessary for photosynthesis as well as red ~650-700 nm wavelength light. Red light-and anything in between blue and red-is easily lost as it penetrates deeper in the water.
Blue light makes things look very bright!! The brightness of your light does not determine its useful output!
A goldfish lover from Norfolk paid hundreds of pounds in vets’ fees when his pet became constipated.
The owner took his ailing fish to Toll Barn Veterinary Centre in North Walsham where vets told him it was constipated and an operation would cost about £300.
Vet Faye Bethell used anaesthetised water to knock out the goldfish before removing the blockages.
“At the end of the day they’re all pets and everybody does have a commitment to their pet,” Miss Bethell said.
“[The goldfish] was constipated because he had a lump blocking his bottom, rather than because of his diet or any other reason,” she said.
The operation, which took almost an hour, was performed by Miss Bethell, assisted by two veterinary nurses.
“We’ve got one nurse who bubbles anaesthetic gas through a tube that goes in through its mouth and over its gills, and then we have a second nurse to monitor with a probe to check the heart rate,” Miss Bethell said.
“Obviously, we discussed all the options [with its owner] and he made the decision to go for surgery.
