Super tall seahorse tank help

[melev]

It isn't about heat in this case. You're username indicates you know a lot about seahorses, and I thought they don't handle bright light well. I know some sites even recommend darker substrate so they aren't blinded by the light's reflection off the sand. This also allows them to spot their food (mysis) with the dark background beneath.

The screen should help.

I have to agree with Melev on this lighting situation. If you use VHO, the lighting will not stress your ponies into hiding behind rocks and things in the darker areas of your tank. I think folks may think that Seahorses are difficult to raise, but they really don't need to be. Remember where sea horse's reside in our oceans. They tend to stay by the darker more dense (dirty) area's in the reef. That doesn't mean you should keep a dirty tank, but one that they approve of. Keep your parameters where they should be, do fresh water top offs as a substitute for water changes. A water change may not be necessary if your salinity is high, so don't completely change their natural environment when you can simply top off and lower the natural occurring drop in salinity due to evaporation. You'll have some very pleased ponies if you don't constantly change their environment. Sometimes less is best to keep an even keel! ...Angel
