The thread is 10 years old and the OP hasn't been on since June so you probably won't get a response and if you do I have a feeling they may not be keeping them anymore.
Planetcatfish I have found is an invaluable resource when looking up info on catfish, so ist's a great place to start. I personally never kept Woodsi but according to Planetcatfish they can thrive in a PH range from 5.8-7.0 as long as it's done properly and of course large fluctuations are avoided. Temperatures between 75.2-78.8°F. They display fairly typical Doradid behavior but are one of the most timid of Doradids. So don't ever expect to see them. Lol They are nocturnal. Again this is what Planetcatfish says. Here's link to Woodsi profile page and Catfish of the Month from back in 2005. Hope it helps.
