I'm sorry, DQ. He had a good, long life with you.
Silverfang, if you want plants to really thrive then yes. You would need to get a light fixture that puts out at least 50 watts of light or more - the one I have for my 20 gallon long puts out 48. To get something that bright, you usually have to get a T5-HO (high output) light fixture. Cost can vary but expect it to be over $100. -___- If you aren't going to grow lots of stem plants or low-growing plants or any plant that is red, then what you have is probably fine wattage-wise. You can grow crypts, mosses, java fern, anubias, water sprite, water wisteria, cabomba, and maybe some rotala. Swords may or may not grow well. For the kelvins, OFL said 6500 K simulates natural daylight best. If you got that double bright Marineland LED light that you once talked about finding on kijiji, that probably is bright enough.
Tiki, wow. Prolific snails. O.O
I haven't seen my assassin snails since I put them in the tanks. Hey, Laki, an assassin snail shouldn't bother a substantially bigger mystery snail, should it? I forgot that my mystery snail is in the 20 gal and I couldn't find him to get him out - he was in the plants somewhere. He's about 1 and a half inches in diameter at least, maybe bigger. The assassins are tiny . . .
