Had fish too, well, we are down to one live coral reef tank...Steve the spider would have taken quite a smack to spatter at 8 inches long, he was a biggin! An if he had bitten it would have hurt as his fangs were almost 1/2 inch long but he was very docile as most big spiders are.
Little wolfs spiders are fast and mean, the bite is very painfull, the black widows too, which we have outdoors down here.
The pygmy rattlers and deadly coral snake are all wild here.
Pythons are starting to breed wild, they are going to be a problem. anything that goes after gators , is well, mean
