I just lost $60 worth in hygo and vals thanks to some really ugly plant melt due to transplanting.
My red tiger lotus has sprouted, hornwort & anubias look alright and my narrow leaf chain swords are little brown on the tips but still alive and kickin'
What plants might be easy for a first time planted tank asside from anubias and ferns?
vals always melt, but then come back. i don't know how long you had them in the new tank after "transplanting", but it can take a few weeks or a few months...
most plants undergo an acclimation process when you move it from one tank to another. the leaves will die off, but it will grow new ones.
anubias, java fern, jungle val, ludwigia, rotala indica, amazon sword(need root tabs), dwarf lily, tiger lotus, saggittaria....there's a lot of plants that are easy that i would consider beginner plants that i've had success with.
