Ok so my girlfriend wants eithe angels or convict cichlids. I have a good idea how fast a convict will grow but no clue about angels. I'm thinking of going to petco while they have the $1 a gallon sale and getting either a 20l or 29g tank. Depending on the size of the 29 if it can fit where I plan on doing it. So my question is if I go with the 20 allon long will there be enough room for a 2-4 baby angles and they live comfortably until I can save to get the accessories for my 55? For the lights and stuff I want for my 55 it should take me 6-8 months to get it set up. So can that many baby angels do well for that long or will they grow too fast?
