<human>:  Catriona has 8 goldfish in her aquarium. She has 4 more angelfish than goldfish. Also, she has twice as many guppies as angelfish. How many fish does Catriona have in her aquarium?
<bot>: How many angelfish does Catriona have? ** Catriona has 8 + 4 = <<8+4=12>>12 angelfish.
How many guppies does Catriona have? ** She also has 12 x 2 = <<12*2=24>>24 guppies.
How many fish does Catriona have? ** Thus, she has 8 + 12 + 24 = <<8+12+24=44>>44 fish in her aquarium.
