At the moment I have a 36 by 12 by 18 inches tank (L by D by H)

it contains 2 black widows, and attempt to bring up the shoal ends up in dead tetras, they may have paired whilst being in my cousin's tank alone for 6 months

1 male krib, killed his mate
1 male dwarf gouramy
4 bronze cories

I want to get rid of all these guys (lol) and get some snakeheads! Channa bleheri to be exact

Also have a 5 gallon with 1 male betta, Titan, he is a blue veil tail
