I am keeping Pbass,Arowana,cats, and eventually rays... So i figured 32" would be perfect for all... No one im my area (that i have been able to find) makes or cuts plexiglass... Also its like 2 times the cost (unless you know someone you want to hook me up with)... I would love to do acrylic, but the price is what has set me back... Im trying to keep this at or under 1500.00... so far im doing a good job including the purchase or another FX-5... If you can help me out with that then im completely down... and be ready for me to start buying A BUNCH OF SCRUBBIES hehehehe!!!!!!!
