hi gabby, welcome to fishlore, i don't think he is mental , i think he is scared :-X, put some more tetras.Gabby said:One of my Neon Tetra's goes absolutely insane when i turn off the lights in my tank. Just got him today and not sure why he doesn't like the dark. What to do?!?!?! Thanks!!
Lucy, I have a lot of plants, so of course I also have a lot of lights. What I do is all of my lights are on seperate timers so that only 1 comes on at first, a tiny moonlight LED for an hour, then a smaller 22 watt. After another hour one of the 65 watt lights comes on, 30 minutes later the other 65. This way the light gradually builds up and doesn't blind my fish all at once. Even if you don't have more than 1 light, they make all sorts of cool dim little LED "moonlight" lights. Yo could get 1 of these and switch it on first to wake up your fish before you turn on your main light.Lucy said:My neons also get scared when I turn on the light. It makes me feel so bad.
How do you gradually bring them to light?
