Hello Gary I hope you managed to save the apistos!!! This is one of the reasons, every 5 years or so, i get rid of old tanks and pick up new ones. I had a 20 high develop a fast leak once but never a side pop out. I resealed it and eventually sold it an auction. It didnt leak after sealing it but hey, im not taking that chance again. I've got a couple of tens that are ready to go now too!!! John ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
